If you use Linux then OTPClient works great with Aegis since it can open Aegis export files directly. I’ve set up Aegis to make an export whenever I change something, I sync the exports automatically to my PC, and I open them with OTPClient there.

OTPClient can ask for the export password each time you open it and will close itself automatically if it’s not used for a while.

You can also use it to export the 2FA codes further in various formats, show the QR code for any of them, and all kinds of useful features like that.
