Marketing agencies should manage client passwords in a centralized password manager organized by client. Each client should have a separate vault containing their social media, advertising, website, analytics, email, and other credentials. Access should be limited to the team members working on that account, logged for accountability, and removed immediately when employees or freelancers leave.
- - Marketing agencies should avoid storing client passwords in WhatsApp, Slack, spreadsheets, or employee memory.
- - Organize credentials using one separate vault for each client.
- - Give employees and freelancers access only to the clients and credentials they need.
- - Use individual platform accounts instead of shared passwords whenever possible.
- - Make credential removal part of employee and freelancer offboarding.
- - Keep recovery information, backup codes, ownership details, and login URLs alongside important credentials.
- - Treat client credential management as an access-control process, not simply a password-storage problem.
Why is password management difficult for marketing agencies?
A normal company might manage credentials for its own tools.
A marketing agency manages credentials for everyone else's tools too.
One client may give the agency access to:
- Meta Business Manager
- Google Ads
- YouTube
- TikTok
- WordPress
- Shopify
- Google Analytics
- Search Console
- Mailchimp
- HubSpot
- Domain registrars
- Hosting accounts
Now multiply that by 10, 20, or 50 clients.
Very quickly, credential management becomes an operational problem rather than simply a password problem.
The agency needs to know who has access, where credentials are stored, which account belongs to which client, and what needs to be removed when someone leaves the team.
Where do agencies usually store client passwords?
Many agencies start with whatever is convenient.
Passwords end up inside:
- WhatsApp conversations
- Slack messages
- Google Sheets
- Notion pages
- Email threads
- Project descriptions
- Personal password managers
- Browser saved passwords
- Notes on someone's phone
This works when an agency has three employees and a few clients.
It becomes dangerous when the agency grows.
A password shared in a WhatsApp group six months ago might still be accessible to someone who no longer works on the client.
A spreadsheet might contain credentials for 20 different brands while being shared with the entire agency.
A social media manager may leave the company while still having access to several client accounts.
The problem is not just where the password is stored.
The problem is controlling the lifecycle of that access.
What is the best way to organize client credentials?
A simple model works well:
One client. One vault.
Each client should have a dedicated place containing only that client's credentials.
For example:
Client: Acme Foods
- Meta Business Manager
- Google Ads
- Shopify
- WordPress
- Google Analytics
- Search Console
- Mailchimp
Client: Northstar Hotels
- Google Business Profile
- WordPress
- Booking platform
- Google Ads
This structure makes credentials easier to find and makes permissions easier to understand.
When someone joins the Northstar Hotels account, they get access to the Northstar vault.
They do not automatically get access to every other client's passwords.
Who should have access to client passwords?
Only people who need the credential to perform their work.
A designer creating Instagram creatives probably does not need the client's domain registrar password.
A performance marketer might need Meta Ads and Google Ads but not Shopify administrator access.
A freelance video editor may not need passwords at all.
Access should follow the principle of least privilege: give people the minimum access required to perform their job.
Agencies can structure access around:
- Client
- Team
- Role
- Project
- Individual credential
The exact model depends on the agency, but access should never default to "everyone can see everything."
Should agencies share passwords through WhatsApp or Slack?
Preferably not.
Messaging apps are excellent for communication.
They are poor systems for credential management.
Once a password enters a group conversation, controlling where that password goes becomes difficult.
Someone can copy it.
Someone can forward it.
Someone can screenshot it.
Someone joining the conversation later may also gain access depending on how the platform works.
More importantly, there is usually no clean connection between the credential and the client's account structure.
The better approach is to send a reference to where the credential is securely stored rather than sending the password itself.
Are spreadsheets safe for managing client passwords?
Spreadsheets are convenient but become risky as an agency grows.
Consider a sheet containing credentials for 30 clients.
Giving someone access to that sheet may expose credentials for clients they do not work with.
There are other operational problems too.
It becomes difficult to answer:
- Who viewed this password?
- Who changed it?
- When was it changed?
- Who currently has access?
- Which credentials should this employee lose when they leave?
- Which client passwords need rotation?
A spreadsheet can store information.
It is not designed to manage credential access.
What happens when an employee leaves the agency?
Offboarding should include credential removal.
The agency should identify every client account the employee could access and remove that access immediately.
A basic offboarding checklist should include:
- Disable the employee's agency account.
- Remove access to client credential vaults.
- Remove the employee directly from client platforms where possible.
- Rotate shared passwords they previously knew.
- Review administrator permissions.
- Check recovery emails and phone numbers.
- Confirm that client accounts still have valid owners and backup administrators.
This process becomes much easier when credentials are already organized by client.
Instead of asking, "What passwords did this person know?"
You can ask, "Which client vaults did this person have access to?"
Should agencies use shared client accounts?
Whenever a platform supports individual user access, use it.
For example, instead of five people sharing one administrator username and password, invite individual users when the platform allows it.
This makes access easier to revoke and reduces the number of passwords that need to be shared.
Shared credentials are sometimes unavoidable.
When they are, store them centrally and control who can reveal them.
How should agencies handle freelancers?
Freelancers should be treated as temporary access holders.
Give them only the credentials required for the project.
Avoid giving freelancers permanent access to a vault containing every credential associated with the client.
When the project ends:
- Remove vault access
- Remove platform permissions
- Rotate shared credentials if necessary
This is particularly important for agencies that frequently assemble project-based creative teams.
What should a client credential vault contain?
A client vault should contain more than just usernames and passwords.
Useful information can include:
- Login URL
- Username
- Password
- Account ID
- Recovery email
- Recovery phone
- Backup codes
- API keys
- Security questions
- Expiration date
- Who owns the account
- Notes explaining what the account is used for
The goal is to make the credential understandable even if the person who originally added it is unavailable.
How should agencies handle two-factor authentication?
Two-factor authentication should be enabled whenever possible.
However, agencies also need to think about ownership.
Using one employee's personal phone number as the only way to access a major client's account creates another dependency.
Where possible, agencies should use systems that allow multiple authorized users, securely stored recovery codes, or organization-controlled authentication methods.
The important question is:
What happens if the person holding the second factor is unavailable tomorrow?
If the answer is "the agency loses access," the setup needs improvement.
How often should client passwords be changed?
Passwords do not necessarily need to be changed on an arbitrary monthly schedule.
They should be changed when there is a reason.
Common triggers include:
- An employee leaves
- A freelancer finishes a project
- A credential was accidentally shared
- Suspicious login activity appears
- A device containing credentials is lost
- The client changes agencies
- Someone who previously knew the password should no longer have access
The agency should also review important accounts periodically to confirm that the correct people still have access.
What should agencies do when onboarding a new client?
Credential organization should be part of client onboarding.
Instead of asking clients to send passwords through WhatsApp, send them a structured list of required access.
For example:
- Meta Business Manager access
- Instagram access
- Google Ads access
- Google Analytics access
- Search Console access
- Website CMS access
- Email marketing access
Whenever possible, request delegated user access instead of passwords.
If a shared credential is necessary, add it directly to the client's credential vault.
This creates a clean starting point for the relationship.
What should agencies do when a client leaves?
Client offboarding matters just as much as onboarding.
When the relationship ends:
- Confirm which accounts belong to the client.
- Return or transfer administrator control where necessary.
- Remove agency users from client platforms.
- Remove freelancers and former employees.
- Ask the client to rotate shared credentials.
- Archive or delete stored credentials according to your agreement and retention policy.
A professional handover reduces security risk and creates a better final experience for the client.
What does a good agency password management system look like?
A good system should make four things obvious:
Who owns the credential?
Which client does it belong to?
Who currently has access?
What happens when that person's access should end?
The technology matters, but the structure matters just as much.
For most agencies, the simplest model is still:
One client.
One vault.
Only the right people get access.
And access disappears when they no longer need it.
Frequently Asked Questions
What is the best password manager setup for a marketing agency?
A marketing agency should use separate credential vaults for each client and grant access only to the employees or freelancers working on that account. This prevents one shared password database from exposing every client's credentials to the entire agency.
Can marketing agencies store client passwords in Google Sheets?
They can technically store passwords in a spreadsheet, but it is not a good long-term credential management system. Spreadsheets make granular access control, credential history, auditing, and employee offboarding harder.
Should marketing agencies share client passwords on WhatsApp?
No. Client passwords should ideally be stored in a dedicated credential management system rather than WhatsApp or other messaging applications. Messaging platforms make it difficult to control where credentials are copied or who retains access later.
How should agencies manage passwords for multiple clients?
Create a separate vault for each client. Store that client's social media, advertising, website, analytics, email, and other credentials inside the vault, then provide access only to team members working with that client.
How should agencies manage passwords when employees leave?
Immediately remove the employee's vault and platform access. Shared passwords the employee knew should be rotated, and administrator, recovery, and two-factor authentication settings should be reviewed.
Should freelancers get access to client passwords?
Only when necessary. Freelancers should receive the minimum access required for their project, and that access should be removed once their work is complete.
Is it better to share a password or invite a team member to an account?
When a platform supports individual users, inviting the person is usually better. Individual access can be revoked without changing a password used by the rest of the team.
What credentials do marketing agencies usually need to manage?
Common credentials include Instagram, Facebook, Meta Business Manager, Google Ads, LinkedIn, TikTok, YouTube, WordPress, Shopify, Google Analytics, Search Console, email marketing platforms, domains, hosting accounts, and other client marketing tools.
