If you’re not signed in with the account you want to remove, you’ll need to do that first. From your profile, tap the three lines at the top-right, select Settings, scroll down and tap Add Account > Log into existing account. Then choose the account you want to remove to sign in.
Even though this account will no longer show up on the Instagram sign-in screen, the username and password might be saved to your phone or tablet. This could cause the username and password to show as a suggestion when you log in to Instagram in the future (even in a web browser). You can delete the account’s saved login info from Keychain (iPhone/iPad) or Chrome (Android).
If you have already removed the account from Instagram but still see the username and password as a suggestion, removing it from Keychain will solve the problem. Removing the Instagram account from Keychain will also ensure that the password is no longer suggested in Safari when you’re using your Mac.
Confirm your thumbprint or use Face ID to continue.
Removing the saved login from Chrome also ensures that you won’t see this Instagram account in your saved passwords in Chrome on your computer.
