Issue with Google Smart Lock about krypton-ios

[hugo]

@kcking, since upgrading to iOS 13, Smart Lock no longer prompts to open Krypton when following the instructions and instead asks to pair a bluetooth device:

Turns out it also doesn't work in Safari itself either. If i go to accounts.google.com, do the whole procedure, eventually it'll open Krypton, I'll OK the request and then bam back in Safari it opens a new tab and 400 again.

Sorry for the inconvenience. If you ever need to revert to normal Smart Lock behavior, uninstalling Krypton and restarting your phone will reset which apps handle the u2f app-link. (This is an unfortunate limitation of iOS)

Are you by any chance logging in in an incognito tab?

Unfortunately uninstalling Krypton also means losing my GPG and SSH keys.

Not using an incognito tab no. I managed to work around it by having Smart Lock accept a backup code in the mean time, but it would be great to figure out what's going wrong in the interaction here. It seems to almost work!

@daenney are you trying to login to smart lock with Krypton? This is not currently supported -- only logging in to iOS settings and logging in with safari is currently supported. We're working on adding support for Chrome iOS and Smart Lock (if possible).

We updated this blog post with setup instructions: https://krypt.co/blog/posts/use-google-advanced-protection-with-krypton.html#setup-instructions

Please re-open this issues if you're still facing issues!

HI. I tried to follow these instructions, but it fails. Upon accepting the request in Krypton a message appears "Unknown error "noKnownKeyHandle"". I recently switched phones, and besides a lot of other issues, this is the only one remaining. I can use the login for other services though (Github, Gitlab working fine).
