Generated passwords for users created through integrated authentication

GitLab allows users to set up accounts through integration with external authentication and authorization providers.

These authentication methods do not require the user to explicitly create a password for their accounts. However, to maintain data consistency, GitLab requires passwords for all user accounts.

For these accounts, GitLab uses the friendly_token method provided by the Devise gem to generate a random, unique, and secure password. GitLab sets this password as the account password during sign up.

The length of the generated password is 128 characters.
