Sign-up restrictions

You can use sign-up restrictions to:

• Disable new signups.
• Require user email confirmation.
• Blacklist or whitelist email addresses belonging to specific domains.

Disable new signups

When this setting is enabled, any user visiting your GitLab domain will be able to sign up for an account.

You can restrict new users from signing up by themselves for an account in your instance by disabling this setting.

Recommendations

For customers running public facing GitLab instances, we highly recommend that you consider disabling new signups if you do not expect public users to sign up for an account.

Alternatively, you could also consider setting up a whitelist or blacklist on email domains to prevent malicious users from creating accounts.

Require email confirmation

You can send confirmation emails during sign-up and require that users confirm their email address before they are allowed to sign in.

Minimum password length limit

You can change the minimum number of characters a user must have in their password using the GitLab UI.

Whitelist email domains

You can restrict users to only sign up using email addresses matching the given domains list.

Blacklist email domains

With this feature enabled, you can block email addresses of a specific domain from creating an account on your GitLab server. This is particularly useful to prevent malicious users from creating spam accounts with disposable email addresses.

設定

To access this feature:

1. Navigate to the Admin Area > Settings > General.
2. Expand the Sign-up restrictions section.

For the blacklist, you can enter the list manually or upload a .txt file that contains list entries.

For the whitelist, you must enter the list manually.

Both the whitelist and blacklist accept wildcards. For example, you can use *.company.com to accept every company.com subdomain, or *.io to block all domains ending in .io. Domains should be separated by a whitespace, semicolon, comma, or a new line.
