Hello My friends..!
so is there is a way that i can retore the password from a backup file..?
i want to restore a specific backup from a year in my RB2011 router, but i forget the login pass..?

There are two problems:

  1. you need access to device. So either you have to know current password or you have to wipe whole config
  2. it’s only possible to restore full config from backup, you can’t “cherry-pick” only specific bits

If the backup is old enough, like 6.1x, the password is saved basically as clear text (just an XOR…)
If the backup is of a newer version, the hash with other encryption is saved, so it is impossible to get back the plaintext password without using “brute force”…
The recovery of the access passwords of the RouterBOARD is deliberately almost impossible (without brute force or similar), they are not even in the export.

Try with this if you have older ROS version: https://github.com/BigNerd95/RouterOS-Backup-Tools

Warning
User password format

ROS v6.45.1+ removed insecure password storage, so they cannot be extracted with extract_user.py any more.
