@ElizabethLee you might want to reconsider it:

first, Signal is centralized and depends on phone numbers

second, with #DeltaChat you can use mini-apps in chats, including an app similar to Aegis that you are using, but Aegis is an android app, using the tool inside Delta Chat in your "Saved Messages" notes you can have your 2FA tokens synchronized (with e2e encryption) in all your devices without having to add them manually or the risk of losing them and needing manual backup
