2FA hardware - like onekey

[xchrix]

hey. maybe it was already asked here but didnt find anything
is there a piece of hardware which is able to handle many 2FA codes? like google auth app for android but on a dedicated hardware. i think about a little token with just a alphanumeric single line display. something like trezor. where you put in manually the secret code (no need for a qr scanner).

i think this would be much more safer than a software on an open platform. and you dont have to unlock your phone - open the app - wait for loading - search for the right key...

i have found "onekey" but it looks like its only for singapore bank accounts?!?!

yubikey isnt the right option for me
- it has no battery, so no time available - no google auth codes
- its possible to use a yubikey software to do a challenge-response and get the right key. but then you need this software on the computer you are using (what about mobile login?) and you are only able to store two identities
