Google authenticator supports syncing across multiple devices.
is that new? I migrated at the time from GA to Authy and from Authy to Ente because it was not supported.

So relatively new, and I didn't know this and moved to proton for this reason recently.
Another thing to know: in the hamburger menu there is a "require face id option". Turn it on, otherwise if your phone is snatched from you (while unlocked), they can access your 2-factor codes.
