Switch user in terminal?

Hi.

I created ssh keys under a 2nd user. How can I change the user in the Mikrotik Terminal?

Like on Linux:
su user2

Just tested

/system ssh 127.0.0.1 user=…

should work (provided you have accept input rule for 127.0.0.1, which I think default is available on most devices)

You can also simply start from Linux/Windows with ssh ?

thank you very much, that worked.
But we use another SSH port and had to change that

/system ssh 127.0.0.1 port=11256 user=user
