What you can do
Link a device
New browsers or phones must complete the product’s device link / approval flow before they can decrypt history.
Revoke a device
Remove lost or unused devices so they stop receiving new wraps for your conversations.
Compromised endpoint
E2EE cannot protect messages on a phone malware already controls. Revoke, rotate recovery, and secure the device OS.
