If you use Aegis on Android and use a Gnome-based Linux distro, I highly recommend complementing with Gnome Authenticator[1][2][3][4].
flatpak install flathub com.belmoussaoui.Authenticator
Gnome Authenticator is still a little early and buggy (mainly performance issues when you have lots of tokens), but it can import and export Aegis format (and a few others). It's been downright luxurious having my seeds on my phone and my laptop and desktop.[1] https://gitlab.gnome.org/World/Authenticator

[3] I think (I hope) that Gnome Authenticator will be distributed as part of Gnome at some point in the future, but it isn't yet
[4] It's also super easy to build and run from source using Gnome Builder[5]. Just open Builder and clone the source from gitlab, and click the "Build" button and it will do its thing
