# Custom password length limits
|
|
|
|
By default, GitLab supports passwords with:
|
|
|
|
- A minimum length of 8.
|
|
- A maximum length of 128.
|
|
|
|
GitLab administrators can modify password lengths:
|
|
|
|
- Using configuration file.
|
|
- [From](https://gitlab.com/gitlab-org/gitlab/merge_requests/20661) GitLab 12.6, using the GitLab UI.
|
|
|
|
## Modify maximum password length using configuration file
|
|
|
|
The user password length is set to a maximum of 128 characters by default.
|
|
To change that for installations from source:
|
|
|
|
1. Edit `devise_password_length.rb`:
|
|
|
|
```sh
|
|
cd /home/git/gitlab
|
|
sudo -u git -H cp config/initializers/devise_password_length.rb.example config/initializers/devise_password_length.rb
|
|
sudo -u git -H editor config/initializers/devise_password_length.rb
|
|
```
|
|
|
|
1. Change the new password length limits:
|
|
|
|
```ruby
|
|
config.password_length = 12..135
|
|
```
|
|
|
|
In this example, the minimum length is 12 characters, and the maximum length
|
|
is 135 characters.
|
|
|
|
1. [Restart GitLab](../administration/restart_gitlab.md#installations-from-source)
|
|
for the changes to take effect.
|
|
|
|
NOTE: **Note:**
|
|
From GitLab 12.6, the minimum password length set in this configuration file will be ignored. Minimum password lengths will now have to be modified via the [GitLab UI](#modify-minimum-password-length-using-gitlab-ui) instead.
|
|
|
|
## Modify minimum password length using GitLab UI
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/merge_requests/20661) in GitLab 12.6
|
|
|
|
The user password length is set to a minimum of 8 characters by default.
|
|
To change that using GitLab UI:
|
|
|
|
In **Admin Area > Settings** (`/admin/application_settings`), go to the section **Sign-up restrictions**.
|
|
|
|
[Minimum password length settings](../user/admin_area/img/minimum_password_length_settings_v12_6.png)
|
|
|
|
Set the **Minimum password length** to a value greater than or equal to 8 and hit **Save changes** to save the changes.
|
|
|
|
CAUTION: **Caution:**
|
|
Changing minimum or maximum limit does not affect existing user passwords in any manner. Existing users will not be asked to reset their password to adhere to the new limits.
|
|
The new limit restriction will only apply during new user sign-ups and when an existing user performs a password reset.
|
|
|
|
<!-- ## Troubleshooting
|
|
|
|
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
|
|
one might have when setting this up, or when something is changed, or on upgrading, it's
|
|
important to describe those, too. Think of things that may go wrong and include them here.
|
|
This is important to minimize requests for support, and to avoid doc comments with
|
|
questions that you know someone might ask.
|
|
|
|
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
|
|
If you have none to add when creating a doc, leave this section in place
|
|
but commented out to help encourage others to add to it in the future. -->
