At the recommendation of some of those here, and with the help of a webcam to capture my Authenticator QR code, I successfully moved everything over to Aegis. I set up a strong password, stored in my password vault. Aegis lets you do biometric login. Took a screenshot of Authenticator's export QR code via the webcam, then added it with Aegis. Then went to Aegis's Settings->Backup and exported a JSON backup, which is encrypted with the password. That's a bit more peace of mind.
