Multi-factor authentication apps are very critical pieces of software, so we are generally careful with what we recommend.
In the case of Aegis, one of our members has done an analysis of it in the past, and it looked (and I feel like it probably still is) a great choice. You can find that analysis here:
We also prefer to keep recommendations to the best options; options that we are confident in recommending to the community, instead of a list with multiple recommendations of varying or dubious quality.
To be clear, this is not me saying that there’s anything wrong with Authenticator Pro. What I am saying is that there needs to be a good reason for us to switch to recommending this one over Aegis. While it is true that Authenticator Pro has had more recent updates than Aegis, I can see commits in Aegis from 3 days ago, so development is by no means dead.
I would say that unless there are some security or privacy related improvements that Authenticator Pro brings to the table, we shouldn’t currently recommend it, especially in the absence of an analysis similar to the one that we have for Aegis.
