What are some good authenticator apps you trust?

Hi there, hello! Some of you might remember me from when I was asking about passwords and passkeys. today I've come to ask about authenticator apps, I mostly plan to make the move to passkeys once I get a better phone but for the moment i was wondering what are some good authenticator apps? I was originally gonna use bitwardens authenticator but at the same time I use bitwardens password manager and I know it wouldn't be smart to have my 2fa codes in the same basket.
