 - `GITLAB_SECRETS_OTP_KEY_BASE` is used to encrypt 2FA secrets in the database. If you lose or rotate this secret, none of your users will be able to log in using 2FA.
 - `GITLAB_SECRETS_DB_KEY_BASE` is used to encrypt CI secret variables, as well as import credentials, in the database. If you lose or rotate this secret, you will not be able to use existing CI secrets.
 - `GITLAB_SECRETS_SECRET_KEY_BASE` is used for password reset links, and other 'standard' auth features. If you lose or rotate this secret, password reset tokens in emails will reset.
+- `GITLAB_SECRETS_ENCRYPTED_SETTINGS_KEY_BASE` is used for reading settings from encrypted files such as SMTP or LDAP credentials.
 
 > **Tip**: You can generate a random string using `pwgen -Bsv1 64` and assign it as the value of `GITLAB_SECRETS_DB_KEY_BASE`.
