Pick a username before you start signing up

The fastest way to create a username is to decide on one before you open any account. Write down three or four options you like — something you can remember, spell without thinking, and type quickly. Test each one by saying it aloud to someone else. If they have to ask you to repeat it or spell it, pick a different one.

A good username is short enough to type in under five seconds and doesn't require numbers or special characters unless the site forces you to add them. If you use the same username across multiple sites — email, banking, social media, shopping — pick something that doesn't reveal your real name, birth year, or location. This makes your accounts harder to guess and keeps your personal information private.

Key Takeaways

  • Choose your username before you start creating accounts, and write down your top three choices in case your first pick is already taken.
  • Keep your username short, straightforward to spell, and something you can type from memory without looking at what you wrote down.
  • Avoid usernames that include your real name, birth year, or hometown, since these make your accounts easier to guess.
  • If a site requires numbers or special characters, add them at the end rather than in the middle, so the core username stays memorable.
  • Test your username on the actual site before you finish creating the account — some sites show you when ready if it's already taken.

What happens when your first choice is taken

Most sites tell you right away if someone else already has the username you want. When that happens, the site usually suggests variations — adding a number at the end, swapping a letter for a number that looks similar, or adding an underscore. You can accept one of these suggestions or type in your second choice from the list you prepared.

If you really want a specific username and it's taken, some sites have a way to request it from the current owner or report it as inactive. This rarely works unless the account has been unused for years. Your faster option is to use your second or third choice, or to add a number that means something to you — like a birth year or a favorite number — at the end.

How to make your username work on multiple sites

If you use the same username on email, banking, shopping, and social media, you're making it easier for someone to find all your accounts at once. A better approach is to use one username for sites that hold money or personal information — like your bank, email, and government accounts — and a different username for everything else.

For your primary accounts, pick something completely random that has no connection to your real identity. For social media and shopping, you can use something more personal if you want people to find you. Write down which username you used where, or use a password manager that stores this information. This way you won't forget which username goes with which site when you need to log in months later.

Numbers and special characters: when you need them

Some sites require your username to include at least one number or special character like an underscore, hyphen, or period. When a site forces this requirement, add the number or character at the end of your username rather than in the middle. A username like sarah_2024 is easier to remember and type than sa2rah_04.

If you're adding a number, use something meaningful to you — a favorite number, a year, or a number from a memorable date. Avoid sequential numbers like 123 or 1234, since these are the first thing someone will try if they're guessing. Don't use your birth year or the current year, since these can be guessed if someone knows your age.

Usernames for email accounts

Your email username is the part before the @ symbol. Many email providers — Gmail, Outlook, Yahoo — let you choose this when you create the account. Pick something professional enough that you won't be embarrassed to give it to a doctor's office or a bank, since you'll use this email for important accounts.

Email usernames are permanent or very difficult to change, so spend a moment thinking about whether you'll still like it in five years. Avoid usernames with numbers that date them, like party2015 or student99. A straightforward, timeless username like firstname.lastname or firstnamelastname works for any situation and is straightforward to give over the phone.

Testing your username before you finish

Before you complete the account creation, the site will show you a confirmation screen with your new username. Read it carefully. Make sure the spelling is exactly what you intended, that you didn't accidentally add an extra letter or number, and that it looks the way you want it to look when you see it on screen.

If you notice a mistake, most sites let you go back and change it before you finish. If you've already completed the account and you hate the username, some sites let you change it once or twice, though others don't allow changes at all. Check the account settings or help section to see what your specific site allows. If you can't change it, you may need to create a new account with a different username.

Keeping track of multiple usernames

If you use different usernames on different sites, write them down somewhere safe. A password manager like Bitwarden, 1Password, or the password manager built into your browser can store your username along with your password for each site. This way you don't have to remember which username goes with which account.

If you don't use a password manager, keep a list in a locked document on your computer or in a notebook you keep at home. Include the site name, your username, and any notes about why you chose that particular username. Update this list whenever you create a new account. This takes five minutes now and saves you hours of frustration later when you can't remember whether you used your email address or a username to log in.

Frequently Asked Questions

Can I change my username after I create an account?

It depends on the site. Email providers usually don't allow changes. Social media sites like Twitter and Instagram let you change your username once or multiple times. Banking and government sites rarely allow changes. Check your account settings or the site's help section to see what's allowed before you finish creating the account.

What if I want to use my real name as my username?

You can, but it makes your accounts easier to find and guess. If you use your real name on social media where you want people to find you, that's fine. For banking, email, and shopping, a username that doesn't reveal your identity is safer. You can use your real name as your display name while keeping your actual username private.

Should I use the same username everywhere?

Using the same username on every site makes it easier for someone to connect all your accounts and find personal information about you. A better approach is one username for sensitive accounts like banking and email, and different usernames for social media and shopping. If someone guesses one username, they won't automatically have access to all your accounts.

What makes a username hard to guess?

Avoid your real name, birth year, hometown, pet names, or anything else someone could learn from social media. Don't use common words or sequential numbers. A username that combines random words or letters with a number is harder to guess than one based on personal information. The longer and more random it is, the harder it is to crack.

Can I use spaces or special characters in my username?

Most sites don't allow spaces in usernames. You can usually use underscores, hyphens, or periods instead. Some sites only allow letters and numbers. When you're creating your account, the site will tell you which characters are allowed. If a character doesn't work, try a different one or remove it entirely.
