I've got one of these on my keyring. Been using it for years with github, bitwarden, and a few other websites.

I also use TOTP as a fallback and I have an TOTP database and little rust program on an offline computer in case I lose my phone I still have all my TOTP seeds.

I *hate* TXT based 2-factor. My phone provider sometimes gets stuck and TXTs don't arrive for hours, then they come all as a batch. And it's too easy for someone to impersonate my SIM.
