Changing my username

Your username is the beginning part of the main email address that you created to sign up for your ProtonMail account ( Unfortunately, we cannot change the main login username on your account.

When you created your account, you also created a key that was matched to your username. This key allows you to send and receive emails using ProtonMail’s encryption. Changing your username would change the key that was used to send and receive all the emails in your inbox.

There are two exceptions to this rule:

1. We can remove the characters “. “_” and “-” from your username

This is possible because these characters are treated as transparent by our service. That is, username is the same as user_name and, etc. Once a user takes a specific username, none of these variations can be used for a different account.

2. We can change capital letters to sentence case and vice versa

Usernames and email addresses are not case-sensitive, so these changes are purely cosmetic.

If you would like us make these changes, please contact our support team. Otherwise, you can also create a new account at or add additional usernames to your account. For more information, see Aliases and Addresses in ProtonMail.

If you would like to merge one account into another account, please seeĀ Combining accounts.

    you guys are the best finally someone is thinking and doing a fantastic job. Expand into a shared desktop and storage, its great. Add a delay on the email out box so not everything goes out at 3 am it can go at 8 am and look normal.
    I love what you do, whole family and company on it and waiting for domain name to be possible but love proton mail all the same. Great amazing job.
    Thank you!!!

    If only we can have a login ID that’s different from our email address – this way it’s less susceptible to hacking.

    Good job nonetheless!

    Obviously this ‘anonymous’ person is a shill for protonmail. I’ve found security holes in protonmail, and it’s very clunky to use . . . to boot. And my comments
    don’t seem to make it past the moderators, kind of like dealing with fox news and the republicans.

    You cannot completely change the account username. We can help with changing uppercase/lowercase letters or adding/removing . - _ characters. With a paid account, you can add another address as an alias, or you can open a new account with the desired username.

    Hello PM! How do I keep my username with my custom domain from GoDaddy and bring this to Proton Mail? Just signed up for the Proton Plus.

    Is there any way to check a username’s availability first without having to commit to creating an account at the same time? Yahoo indicates right away in red on the next click if a username is unavailable or unrecognized both on their account creation and login pages. Thanks in advance.

    This is currently not possible for anti-abuse reasons.
