When trying to "Connect to Server" from M1 Mac Mini, it asks for a Password. I don't know of any Password needed to access the Mac Mini M2 or the M1 or where to find the password(s)
Mac mini
Set up file sharing on Mac - Apple Support
When you connect to the M2 Mac mini, I would expect that you are being asked for the password of a user on the M2 Mac mini. Which files you are allowed to access over the network might depend on which M2 Mac mini user account is associated with the remote access.
Is there an expert with Thunderbolt Bridges between a Mini M1 and Mini M2
