That's interesting - I thought apps that didn't go through the App Store but were in "developer mode" were time-limited, but maybe I confused it with "share with family" rather than pure personal solo use.

Sounds like you wrote it in Swift(?), did it also do a good job at the autofill code? That's what I'd expect it to potentially struggle at, as it could be a rare and particularly native feature. But then the APIs should be well standardized for iOS.

Very cool and inspiring stuff!

The autofill code is actually Safari's, not the password manager. The password manager basically just needs to impmlement ASCredentialProviderViewController (https://developer.apple.com/documentation/authenticationserv...) and include the "AutoFill Credential Provider" entitlement and safari will ask if you want to sign in with Kenpass for websites and apps.

For firefox (desktop) it's a bit harder, you have to actually implement login box detection. It works like half the time, but I don't really mind much, because it's not a huge deal to just use the clipboard. Even when using 1Password I would so often find that the password autofill was so broken (or would constantly offer me to save passwords I don't want to, or for things that aren't even login boxes) that I actually actively hated it. When creating logins, I much prefer taking an explicit step to activate my password manager to do so, and when prompting for logging in, it's not a huge deal to simply copy/paste when the simple detection doesn't work.
