If TechIDClient.macOS stops being able to send keys (Send Both, Send User, Send Password) then these steps to update the privacy permissions are the first steps to try.
TLDR (TooLongDidn’tRead) : Remove the Settings -> Privacy -> Accessibility -> TechIDClient, Exit TechIDClient, Start TechIDClient, try to “send” again, and then allow the same permission.
Full Directions:
1. Stop TechIDClient on your mac using the menu (TechIDClient->Quite TechIDClient)
2. Open Settings on your mac
3. Scroll down on the left menu and select “Privacy & Security”
4. Select “Accessibility” on the right.
5. Select “TechIDClient” from the list on the right and then click the little minus symbol on the bottom (-).
6. You should end up with a list that does not include the TechIDClient
7. Open the TechIDClient, and try to send a credential. This will open a permission request dialog.
8. Click “Open System Settings”
9. Turn on the slider on the “TechIDClient” line.
10. Sending should now work in the TechIDClient.
