I have been using Authenci for a long time, since I entered this market! However, it has many inconveniences that make me uncomfortable. This article is really helpful to me. How can I transfer my data to this aegis platform?
Read this.
If you do a backup though, the exported .json file is not encrypted.
I downloaded the app on my old phone to have a play around with, and when I tried to export my database I was met with a pop-up containing a check box for "Keep the database encrypted". I assume you have to have first encrypted the database with a password before being offered this, so perhaps if you haven't added a password then your back ups will be in plain text.
While I think that's a downside of it.
