Email phishing is one of the most common ways for attackers to take over your account or deliver malware to your device. For businesses, targeted phishing attacks are the biggest IT security threat.
As part of our effort to mitigate this threat to our users, Proton Mail(new window) offers a link confirmation feature on all devices. When enabled, you will be asked to confirm that you wish to open an external link from an email.
The feature is enabled by default, but you can turn it off and on in Settings. This article explains how to configure the link confirmation feature on our web, Android, and iOS apps.
Log in to your account at mail.proton.me(new window) and go to Settings → Go to Settings → Proton Mail → Messages and toggle the Confirm link URLs switch on or off.
Android and iOS/iPadOS
Go to Menu (☰) →Settings → Account settings → [account name]→ Mailbox → Privacy and toggle the Request link conformation switch on or off.
