IIRC, it didn't used to give you any control over import/export, and only supported using an opaque Google storage option. Has that changed?

Aegis gives me the actual seed, full control of the data so I can do with it as I please.

You can import/export to Google Authenticator only and you must have two phones. You cannot backup QR codes because screenshot is forbidden for security reason. You cannot migrate to another application.

I just took a pic of the QR codes with my webcam and stored that in KeePass.

Tends not to work to well in the scenario where you drop your phone into the ocean.

Keep away from oceans.

Sounds like a good plan.

Normally one does their backups before they are necessary.
