Verifying your devices
When you log in with Acter in an another device, you might be prompted about "unverified sessions". This is a security measure to ensure only devices you use are logged in and no one else is attempting to spoof your identify and sneak into the system.
It is highly recommended you cross-verify all devices and potential email address of your account whenever you notice this coming up in the βActivitiesβ tab. Notice that a new device is not able to read the history of encrypted messages before it logged on (like WhatsApp or Signal).
