Android System Key Verifier
Safe to disable: com.google.android.contactkeys Safe to disable Vendor documentation
A Google system service that lets you confirm that encrypted chat apps are using the right keys for your contacts. It is safe to disable: you lose nothing most people will miss.
What it does
Android System Key Verifier serves end-to-end encrypted messaging apps. Apps that support it store their users' public encryption keys with it, and you can then compare keys with a contact by scanning a QR code or matching numbers to confirm you are talking to the right person. It does nothing until a supporting app asks it to verify a contact. Google records its releases in a public code transparency log.
If you disable it
Contact key verification stops in apps that support it. Messaging itself keeps working.

Settings offers Disable for this package on most phones. Open Settings > Apps > See all apps > Android System Key Verifier > Disable.
