Aegis on Android is also very nice (and open source).
Check out Aegis if you’re on Android. (See my other comment).
On Android, I replaced Authy with the open-source Aegis app. It’s just as functional, allows exporting, and doesn’t tie your data to your phone number (nor store it on a central system–not sure if Authy does this or not).
You’re not alone in feeling like you bear the weight alone. I mean, with all you’re doing, you’re basically a church-on-wheels here. And I say that both as a compliment and as a reflection of our situation as a society–we need each other, we need neighbors, community, and we need help sometimes. And many people are feeling the “it’s too much to do alone” conclusion. I don’t think we were meant to be this way. I’ve been reading Seth Kaplan’s “Fragile Neighborhoods” recently and I feel like my eyes are open to the deep loss in social capital or “collective efficacy” that previous generations had. We’re in a period of innovating on new social structures. It’s tough. Keep going. Play the long game, make friends and neighbors, and don’t forget you’re just human too. We need each other.
