Recover login password

Hi
is it possible to recover a user login password (for the router) from a non encrypted backup file or by a second user who has full access to the router?

I can find the username in the backup file in clear text, but passwords are stored encrypted. Is it known which format it is?

Thanks in advance for any hints.

If you have another full user, you can reset password of every other user created!
From backup you cannot find it!

It depends on RouterOS version, they recently changed it to not store passwords anymore, only hashes. I don’t remember exact version, but it wasn’t long ago. But if it’s older backup, this works great: http://manio.skyboo.net/mikrotik/

Edit: Don’t be confused by the whole page, you’re only interested in “Password recovery from backups” part at the bottom.
