Admin password login

I have a new AX 3000. I have gone through the process of setting up my admin password several times after rebooting the router to factory settings. Whenever I try to reconnect after setting up a new password, I get a message that I entered the wrong password. I KNOW that I have entered the correct one! What am I doing wrong?

Well, entering the wrong password would solve the mystery here. Even if I trust you you entered the right one it might be still some issue - do you enter by hand or copy from password manager?

Try to login with your password by SSH and see if you enter it right.

Or just reset the whole router and start over.
