Authenticator App: How to choose which one to trust?

[night_driver]

Actually, I wanted to know whether I should keep my secret keys on an encrypted cloud or in local storage. I mentioned Aegis because it’s the most popular among locally stored 2FA apps and Authy among cloud-based 2FA apps.

Multi-device usage is my major consideration after privacy, but that doesn’t mean I’ll use a service with lesser privacy. Thanks to you, I think I should choose Aegis.

Also, I found this comment from another post that helps me strengthen my decision.

Why not use a 2FA authenticator who sync to a third-party cloud sync/backup service?

In a perfect world your 2FA secrets would be on a device that is separate from what you’re logging into, and not just accessible from any of your devices. In reality… if you use the Standard Notes TOTP feature for your 2FA that is probably fine, because Standard Notes has end-to-end encryption, so you don’t have to worry about them accessing your codes. It is just a bit riskier when your codes are accessible from all your devices, you can decide whether that is worth it or not to you.
