Resetting router password

[jiho.a]

Hello,

I would like to know if there's a way to reset the password of router (Cisco MX250) without resetting configurations done already.

It is not clear in your post, so am I correct in assuming that this is a situation where you do not have the current password and want to recover access to the router? This is frequently referred to as password recovery. I do not have experience with MX250 and perhaps it operates differently, but with the Cisco routers that I do have experience with the password recovery process basically involves booting the router without the router loading the startup configuration. Once the router has booted you should be able to get into privileged mode, load the startup config, and configure new passwords. The result of this is that you do not lose the configurations already done.
