Is Proton calling me?

We will never call you unexpectedly. If you’re on the phone with someone claiming to be from Proton support, hang up immediately and do not engage further.

We don’t offer phone support

Proton does not have a call centre or an official contact number. We handle all support processes and customer enquiries by email, with very few exceptions.

Unless you have a scheduled Proton for Business support call booked through your account, any website or caller offering Proton phone support is not genuine.

We will never:

• Call you unexpectedly about an account security issue
• Ask for your Proton Account details, or any other personal details
• Be offended if you choose to hang up and contact us via our official website instead (a scammer will often become pushy, urgent, or upset when you don’t cooperate).

Any email sent from us to your Proton Mail address will have an official “Proton” badge.

If you receive a suspicious call

If someone phones unexpectedly claiming to be from Proton:

• Hang up immediately
• Do not follow any links or instructions from the caller
• Do not visit websites, install software, or share codes mentioned during the call

You should do this even if the caller ID says “Proton”. Scammers can spoof phone numbers.

After hanging up:

1. Check your Proton account

• Open your browser and type in proton.me. Do not use any link provided by the caller.
• Sign in and review your Proton Mail inbox and account settings for alerts or unusual activity.

2. Report the incident to us

• Open a support ticket using our official support form (https://proton.me/support/contact) or email our security team at accountsecurity@proton.me.

If you haven’t shared your information or clicked any links sent by the caller, you shouldn’t need to do anything else.

If you think you may have shared your information with a scammer

If you gave a suspicious caller your details or clicked a link they sent you, secure your account and report the incident to us as soon as possible. Here’s how:

1. Change your password

• Sign in to your Proton Account (type proton.me directly in your browser — don’t click any third-party link).
• Open your account settings (Settings → All settings → Account and password).
• Create a strong, unique password you don’t use anywhere else.​

2. Sign out from all other devices

• Now, go to the Security and privacy page in your account settings.
• Scroll to Session management and click Revoke all other sessions.
• This will sign you out of any other devices, ensuring that nobody else is signed in to your account.

3. Review your security settings

• Go to Settings → Recovery and check that your recovery email and phone number haven’t been changed. If you don’t have recovery methods set up, you should enable them.
• If you have two-factor authentication (2FA) set up, go to Settings → Account and password and check that your details haven’t been changed. If you don’t use 2FA, consider enabling it.

4. Report the incident to us

• Open a support ticket using our official support form (https://proton.me/support/contact) or email our security team at accountsecurity@proton.me.
• Our team will follow up and verify that your account has not been compromised.

How the scam works

The goal of a phishing scam is to convince you to give away your account details. Scammers might:

• Introduce themselves as “Proton Mail support”, “Proton security”, or “Proton customer service”.
• ​Say there has been a security issue, recovery attempt, or a suspicious incident on your account that you must act on immediately.
• Ask you to visit a fake website or click on a link they send you (the pages can often look very similar to our official site).
• Send you a random link by SMS or email and tell you to log in to “fix” a problem.
• Ask for your password, two‑factor authentication (2FA) code, recovery phrase, or recovery codes “to secure your account”.
• Ask you to read out a code you just received by SMS or email.
• Follow up with emails or fake support tickets to appear more legitimate.
• Combine the call with SMS messages (known as “smishing”) or emails to increase pressure.

As of now, we have no indication of any data breach relating to Proton’s systems. If a scammer has obtained your details, it’s likely from public channels or a data leak from another company.

How to protect yourself from phishing scams

• Never share your Proton password, two-factor authentication (2FA) codes, recovery phrase, or other recovery methods with anyone — even if they claim to be from Proton Support.
• Never sign in to Proton using a link provided in a call, SMS, or email. Always type proton.me directly into your browser, or use one of our official apps.
• Treat any unsolicited call claiming to be from Proton as suspicious, and hang up if you are unsure.
• Use strong, unique passwords and enable two-factor authentication (2FA) on your Proton account and other important services.
• Enable Dark Web Monitoring, and consider using Proton Pass (our free password manager) to create and store secure passwords and hide-my-email aliases.
