TOTP Authenticator Browser Terminal emulator Wireguard client I’ve had the weird idea to use libpam-google-authenticator for both SSH and Sudo. Hell, for one machine I don’t even know the password. I just set it to a long random string. If I need root access, I can get a code from my phone! That means I open it A LOT. At one point I also had 4FA for fun. Or 3FA depending on how you look at it. On server - pubkey + password + TOTP On client the private key additionally encrypted with a different password. Anyway…
