Proton Security

Verify Proton alerts before you sign in.

Proton Mail is known for its high security, which makes it a prime target for 'Official' impersonation scams. Scammers send fake alerts claiming your encryption keys are expiring or your account needs urgent verification to bypass their strict security filters.

Security Insight

Proton Mail uses a 'Purple Official' badge for legitimate system emails. Scammers try to imitate this by using purple icons in the email body, but they cannot spoof the official badge in the sender field of the Proton web or mobile app.

How to spot a Proton Mail Phishing Scam

Legitimate Proton communications have very specific security markers. Watch out for these common tactics used to steal access to encrypted mailboxes.

The 'Official Badge' test

Genuine Proton system emails always show a purple 'Official' badge next to the sender's name in the Proton interface. If it's missing, it's a scam.

Fake 'Key Expiry' warnings

A message claiming your encryption keys or 'Mailbox Version' is outdated and you must click a link to 'Upgrade' or lose your emails.

Non-Proton Sender Domains

Official alerts come from @proton.me or @protonmail.com. Scammers use domains like 'proton-secure-access.com' or random 'protonmail.ch' lookalikes.

Request for 'Recovery Phrase'

Any email that asks you to provide your 12-word recovery phrase or your account password is a 100% phishing attempt.

What IsThisSpam checks before you trust a sender

Quick verdicts are useful, but the real value is understanding why something looks safe, uncertain, or risky.

Unusual Link Destinations

Hover over any button. If the URL doesn't lead to 'proton.me' or 'protonmail.com' (e.g., 'proton-login-portal.net'), it is a fake site.

High-Pressure urgency

Messages like 'Your account will be deleted in 12 hours' or 'Final security warning' are designed to make you act without thinking.

Mismatched Interface Colors

Scammers often use old Proton branding or weird purple gradients that don't match the modern, clean design of the Proton ecosystem.

Generic 'Dear User' greetings

Proton usually addresses you by your account name or doesn't use a generic greeting at all in their official security notifications.
