Where browsers and devices store your usernames

When you log into a website or app, your device offers to remember your username for next time. That username gets stored in different places depending on what you're using: your web browser keeps a list, your phone's operating system maintains another, and some apps store them separately in their own settings. The reason this matters is that deleting remembered usernames from one place won't clear them everywhere.

Remembered usernames are not passwords — they're just the text you typed in the username field. Still, if you share a device or want to keep your accounts private, removing them is a straightforward process once you know where to look.

Key Takeaways

  • Remembered usernames live in your browser's autofill settings, your phone's system settings, and sometimes in individual apps — you may need to clear them from multiple places.
  • Deleting a remembered username from your browser does not delete it from your phone, and vice versa.
  • The steps differ between Chrome, Firefox, Safari, and Edge, and between iPhone and Android.
  • Some apps store usernames in their own login settings rather than using your device's autofill, so check the app itself if the username still appears after clearing your browser.

Clearing remembered usernames in Chrome

Open Chrome and go to Settings in the top right menu (three vertical dots). Select Autofill and passwords from the left sidebar, then click Passwords.

You'll see a list of websites where Chrome has saved your login information. Find the site whose username you want to remove, click the three dots next to it, and select Delete. This removes both the username and password. If you want to keep the password but only remove the username from autofill, that's not possible in Chrome — deleting the entry removes both together.

If the username appears in the autofill suggestions when you type but you don't see it in the Passwords list, it may be stored in Chrome's general autofill data instead. Go back to Settings, select Autofill and passwords, then Addresses and more. Look for the username there and delete it.

Clearing remembered usernames in Firefox

Open Firefox and click the menu button (three horizontal lines) in the top right. Select Settings, then Privacy & Security in the left sidebar. Scroll down to Logins and Passwords and click Saved Logins.

A window opens showing all saved usernames and passwords. Find the site you want to remove, click it to select it, and click the Remove button. Like Chrome, Firefox removes the username and password together — you cannot delete one without the other.

Clearing remembered usernames in Safari

On Mac, open Safari and go to Safari menu at the top, then Settings. Click the Passwords tab. You'll see a list of saved usernames and passwords. Find the site, click it, and click the minus button (–) at the bottom to delete it.

On iPhone or iPad, go to Settings > Passwords (or Passwords & Accounts depending on your iOS version). Find the site in the list, swipe left on it, and tap Delete. If you don't see a Passwords option in Settings, your device may be storing these in iCloud Keychain instead — check Settings > [Your Name] > iCloud > Keychain and turn it off if you want to stop syncing saved usernames across devices.

Clearing remembered usernames in Microsoft Edge

Open Edge and click the menu button (three dots) in the top right. Select Settings, then Passwords in the left sidebar. Click Manage passwords.

Find the site whose username you want to remove and click the three dots next to it, then select Delete. Edge removes the username and password together, like Chrome and Firefox.

Clearing remembered usernames on Android

Android stores usernames in two places: in your Google account (which syncs across devices) and in individual apps.

To clear usernames from your Google account, open Settings and search for "passwords" or go to Google > Manage your Google Account > Security. Look for Password Manager and open it. Find the site, tap it, and select Delete.

If a username still appears when you open an app, the app may be storing it separately. Open the app, go to its settings or account section, and look for a login or password management option. The exact location varies by app — some put it in a menu, others in account settings.

Clearing remembered usernames on iPhone

iPhones store usernames in iCloud Keychain, which syncs across all your Apple devices. Go to Settings > Passwords (on newer iOS versions) or Settings > [Your Name] > iCloud > Keychain (on older versions).

Find the site in the list, tap Edit in the top right, select the entry, and tap Delete. If you turn off iCloud Keychain entirely, all saved usernames and passwords will be removed from your device and stop syncing to your other Apple devices — use this only if you want to clear everything at once.

What to do if a username keeps reappearing

If you delete a username but it still shows up in autofill suggestions, it may be stored in multiple places. Check your browser's general autofill settings (not just the passwords section), your phone's system settings, and the app itself.

Another reason a username might reappear is if you're syncing across devices. If you use Chrome on both a computer and phone, deleting the username on one device may not remove it from the other if they're not synced yet. Wait a few minutes for the devices to sync, or manually delete it from each device.

If you share a device with others and want to prevent anyone from seeing your usernames, consider using your browser's private or incognito mode, which does not save usernames or passwords by default.

Frequently Asked Questions

Does deleting a remembered username also delete the password?

In most browsers — Chrome, Firefox, Safari, and Edge — deleting a saved login entry removes both the username and password together. You cannot delete just the username and keep the password. If you need to keep the password but remove the username from autofill, you would need to delete the entry and manually re-enter the password next time you log in.

Will deleting a username from my browser also delete it from my phone?

No. Your browser and your phone store usernames separately. Deleting from Chrome on your computer does not affect Chrome on your phone, and deleting from your phone's system settings does not affect your browser. You need to delete from each device individually. If you use a synced account like Google or iCloud, the deletion may eventually sync across devices, but this is not when ready.

Can I delete a username without deleting the password?

Most browsers do not offer this option — they treat the username and password as a single entry. However, some password managers allow you to edit entries and remove the username while keeping the password. If this is important to you, consider using a dedicated password manager instead of your browser's built-in autofill.

Why does my username still appear after I deleted it?

The username may be stored in more than one place. Check your browser's general autofill settings (separate from the passwords section), your phone's system settings, and the app itself. Also check whether you're syncing across devices — if you deleted it on your computer but your phone is still synced to your account, it may reappear on the phone.

What's the difference between deleting a username and turning off autofill?

Deleting a username removes that specific entry from your device's memory. Turning off autofill disables the feature entirely, so no usernames or passwords will be suggested or saved going forward. If you only want to remove one username, delete the entry. If you want to stop saving usernames altogether, turn off autofill in your browser or phone settings.
