Same here, though I’m starting to move my OTP over to Bitwarden as well. Way more convenient - as a developer, I spend a lot of time off my phone. Makes more sense to let Bitwarden manage those so I don’t have to pick up my phone as often.
I’m also slightly distrustful of closed-source Authy, whereas Bitwarden is open source and audited for security by third parties.
You can set Bitwarden to require your master password for higher security logins. I keep a separate vault for work and personal things… Everything in my work vault requires it’s master password to use them. The OTPs are useless without credentials, and you need the master password to get at those even when the vault is unlocked. YMMV but to me, this was “good enough” to ensure a separation of concerns between low and high risk.
