Authenticator App of choice?

[stoofa]

Is there a favourite Authenticator app out there people are using?
Obviously big names like Google, Microsoft etc.
I've got a couple of things I'm using SMS authentication on that I'd like to move to an app and things I should have 2fa switched on for that I currently don't.

Cheers for the replies - I'll take a look at the suggestions made.

I am right in thinking that apps like Authy, Google, Microsoft (and others) all use the same standard?
So where a site or service advertises the fact you can setup a "Google Authenticator" you can in fact use any that conforms to the same standard?

Bit like shops that used to display "Apple Pay" stickers, but we all knew if they accepted Apple Pay then Android Pay was going to work.
