## Fully supported hashing methods The most current mailcow fully supports the following hashing methods. The default hashing method is written in bold: - **BLF-CRYPT** - SSHA256 - SSHA512 The methods above can be used in `mailcow.conf` as `MAILCOW_PASS_SCHEME` value. ## Read-only hashing methods The following methods are supported **read only**. - MD5-CRYPT - PLAIN-MD5 - SHA512-CRYPT That means mailcow is able to verify users with a hash like `{PLAIN-MD5}1a1dc91c907325c69271ddf0c944bc72` from the database. The value of `MAILCOW_PASS_SCHEME` will _always_ be used to encrypt new passwords. --- > I changed the password hashes in the "mailbox" SQL table and cannot login. A "view" needs to be updated. You can trigger this by restarting sogo-mailcow: `docker-compose restart sogo-mailcow`
