## Why this matters

A quiet account takeover can continue while you assume your mailbox is safe. Privacy is easier to defend before this information is collected than after it has spread.

## The protection

Proton offers authentication logs that can help you spot unexpected sign-ins.

## Take action

Review logs after a suspicious message or device loss, then change credentials and revoke sessions as needed. Email protection depends on the route and settings. Ordinary mail involving outside providers is not automatically end-to-end encrypted, and email metadata is not universally hidden.
