When working with GitLab tokens, you might encounter the following issues.
If an existing access token is in use and reaches the expires_at value, the token
expires and:
Requests made using this token return a 401 Unauthorized response. Too many
unauthorized requests in a short period of time from the same IP address
result in 403 Forbidden responses from GitLab.com.
For more information on authentication request limits, see Git and container registry failed authentication ban.

Prerequisites:
You must:
api_json.log file.To identify which 401 Unauthorized requests are failing due to
expired access tokens, use the following fields in the api_json.log file:
| Field name | Description |
|---|---|
meta.auth_fail_reason | The reason the request was rejected. Possible values: token_expired, token_revoked, insufficient_scope, and impersonation_disabled. |
meta.auth_fail_token_id | A string describing the type and ID of the attempted token. |
When a user attempts to use an expired token, the meta.auth_fail_reason
is token_expired. The following shows an excerpt from a log
entry:
{
"status": 401,
"method": "GET",
"path": "/api/v4/user",
...
"meta.auth_fail_reason": "token_expired",
"meta.auth_fail_token_id": "PersonalAccessToken/12",
}
meta.auth_fail_token_id indicates that an access token of ID 12 was used.
From GitLab 18.9, meta.user will also be populated with any username associated with the token used for the failed request.
To find more information about this token, use the personal access token API. You can also use the API to rotate the token.
To replace the token:
https://gitlab.com/api/v4/personal_access_tokens,
and locate tokens with a specific expires_at date.401 responses.Delay the expiration of certain tokens with this script.
From GitLab 16.0, all access tokens have an expiration date. After you deploy at least GitLab 16.0, any non-expiring access tokens expire one year from the date of deployment.
If this date is approaching and there are tokens that have not yet been rotated, you can use this script to delay expiration and give users more time to rotate their tokens.
This script extends the lifetime of all tokens which expire on a specified date, including:
For group and project access tokens, this script only extends the lifetime of these tokens if they were given an expiration date automatically when upgrading to GitLab 16.0 or later. If a group or project access token was generated with an expiration date, or was rotated, the validity of that token is dependent on a valid membership to a resource, and therefore the token lifetime cannot be extended using this script.
To use the script:
{{< tabs >}}
{{< tab title="Rails console session" >}}
sudo gitlab-rails console.extend_expiring_tokens.rb script from the following section.
If desired, change the expiring_date to a different date.{{< /tab >}}
{{< tab title="Rails Runner" >}}
In your terminal window, connect to your instance.
Copy the entire extend_expiring_tokens.rb script from the following section, and save it as a file on your instance:
extend_expiring_tokens.rb.expiring_date to a different date.git:git.Run this command, changing /path/to/extend_expiring_tokens.rb
to the full path to your extend_expiring_tokens.rb file:
sudo gitlab-rails runner /path/to/extend_expiring_tokens.rb
For more information, see the Rails Runner troubleshooting section.

On GitLab Self-Managed or GitLab Dedicated instances, administrators can restore personal access tokens that were revoked accidentally. Restoration is not available on GitLab.com.
[!warning] Running the following commands changes data directly. This could be damaging if not done correctly, or under the right conditions. You should first run these commands in a test environment with a backup of the instance ready to be restored, just in case.
Open a Rails console.
Restore the token:
token = PersonalAccessToken.find_by_token('<token_string>')
token.update!(revoked:false)
For example, to restore a token of token-string-here123:
token = PersonalAccessToken.find_by_token('token-string-here123')
token.update!(revoked:false)
Access tokens that have no expiration date are valid indefinitely, which is a security risk if the access token is divulged.
To manage this risk, when you upgrade to GitLab 16.0 and later, any personal, project, or group access token that does not have an expiration date automatically has an expiration date set at one year from the date of upgrade.
In GitLab 17.3 and later, this automatic setting of expiry on existing tokens has been reverted, and you can disable expiration date enforcement for new access tokens.
If you are not aware of when your tokens expire because the dates have changed, you might have unexpected authentication failures when trying to sign into GitLab on that date.
To manage this issue, you should upgrade to GitLab 17.2 or later, because these versions contain a tool that assists with analyzing, extending, or remove token expiration dates.
If you cannot run the tool, you can also run scripts in GitLab Self-Managed instances to identify tokens that either:
You run these scripts from your terminal window in either:
The specific scripts you run differ depending on if you have upgraded to GitLab 16.0 and later, or not:
After you have identified tokens affected by this issue, you can run a final script to extend the lifetime of specific tokens if needed.
These scripts return results in the following format:
Expired group access token in Group ID 25, Token ID: 8, Name: Example Token, Scopes: ["read_api", "create_runner"], Last used:
Expired project access token in Project ID 2, Token ID: 9, Name: Test Token, Scopes: ["api", "read_registry", "write_registry"], Last used: 2022-02-11 13:22:14 UTC
For more information on this, see incident 18003.
This script finds tokens that expire on a specific date.
Prerequisites:
To use it:
{{< tabs >}}
{{< tab title="Rails console session" >}}
sudo gitlab-rails console.expired_tokens.rb from the following section
or expired_tokens_date_range.rb script from the section after that, and paste it into the console.
Change the expires_at_date to the date one year after your instance was upgraded to GitLab 16.0.{{< /tab >}}
{{< tab title="Rails Runner" >}}
In your terminal window, connect to your instance.
Depending on your needs, copy either the entire expired_tokens.rb from the following section
or expired_tokens_date_range.rb script from the section after that, and save it
as a file on your instance:
expired_tokens.rb.expires_at_date to the date one year after your instance was upgraded to GitLab 16.0.git:git.Run this command, changing the path to the full path to your expired_tokens.rb file:
sudo gitlab-rails runner /path/to/expired_tokens.rb

expired_tokens.rbThis script requires you to know the exact date your GitLab instance was upgraded to GitLab 16.0.
# Change this value to the date one year after your GitLab instance was upgraded.
expires_at_date = "2024-05-22"
# Check for expiring personal access tokens
PersonalAccessToken.for_user_types(:human).where(expires_at: expires_at_date).find_each do |token|
if token.user.blocked?
next
# Hide unusable, blocked PATs from output

end
end
[!note] To hide and also remove tokens belonging to blocked users, add
token.destroy!directly belowif token.user.blocked?. However, this action does not leave an audit event, unlike the API method.
This script finds tokens that expire in a particular month. You don't need to know the exact date your instance was upgraded to GitLab 16.0. To use it:
{{< tabs >}}

sudo gitlab-rails console.expired_tokens_date_range.rb script from the next section.
If desired, change the date_range to a different range.{{< /tab >}}

This script identifies dates when most of tokens expire. You can use it in combination with other scripts on this page to identify and extend large batches of tokens that may be approaching their expiration date, in case your team has not yet set up token rotation.
The script returns results in this format:
42 Personal access tokens will expire at 2024-06-27
17 Personal access tokens will expire at 2024-09-23
3 Personal access tokens will expire at 2024-08-13

This script finds tokens that lack an expiration date: expires_at is NULL. For users
who have not yet upgraded to GitLab version 16.0 or later, the token expires_at
value is NULL, and can be used to identify tokens to add an expiration date to.
