Since ProtonMail is a secure email service that prioritizes privacy and security, resetting your password is a bit different from “regular” webmail providers like Gmail. You can do it, but here’s what you need to know.
Before resetting your password
ProtonMail has two password modes: single password mode and dual password mode. If you have not enabled the two-password mode, don̵
In single password mode, the same password is used to login and decrypt your inbox. In the two password mode, you have one password to log in (your account password) and another to decrypt your mailbox (your mailbox password). ProtonMail itself cannot access your passwords regardless of the mode you use.
If you are using the two password mode, changing one of your passwords will put you in the single password mode by default. When the password used to decrypt your mailbox is changed, you will no longer be able to read your old emails. If you later remember, you can restore access to your older emails by restoring the decryption key.
Regardless of which password mode you use, changing your password will cause your older emails to no longer be readable. You can still see unencrypted information such as the sender, subject line, and metadata, but you cannot read the message text or open attachments.
When you create a new password, you also create a new key that will be used to decrypt the data stored in your inbox. You can only read emails sent or received after the reset as they will be encrypted with the new key.
Reset your ProtonMail password via recovery email
This method assumes you set up a recovery email when you registered your ProtonMail account. To reset your account password, go to mail.protonmail.com and click the “Get help” link under the “Login” button.
Are you using the two-password mode? To reset your mailbox password, log in with your account password. Then on the “Decrypt Mailbox” screen, use the “Forgot password” link and follow the rest of the process as normal.
Click on “Reset Password” and enter your ProtonMail username and a recovery email. This email address must match the email address you provided when you signed up.
Confirm your decision in the box that appears and understand that by proceeding you will not be able to decrypt the contents of your inbox. In the next step, you will receive a recovery code, but make sure to leave the recovery web page open while you wait for the email.
Warning: This will erase all emails in your account. You will regain access to your account, but all your previously received emails will be gone. You will still receive emails sent to the address in the future.
Once you have the email, enter the recovery code followed by the “Reset Password” button. Another window will pop up warning you what will happen to your inbox if you proceed to the next step.
Enter the word “DANGER” in capital letters in the box to confirm your decision, followed by the “Reset” button.
Finally, enter a new password and write it down in a safe place (such as a password manager). Press “Reset Password” to complete the process. You can now go back to mail.protonmail.com and log in with your new password.
Re-enable additional security when you are done
Resetting your password disables two password and two-factor authentication mode. If you want to continue using these features, make sure to re-enable them in Settings> Account (two-password mode) and Settings> Security (two-factor authentication).
