Changing Internet username and passwords

Changing your Internet username or password is based on your Internet Service Provider (ISP) and what their policy is for changing the username and password. Often, most ISPs allow you to change your password whenever it's needed. However, they typically do not allow the account username to be changed.

Because every Internet Service Provider and web host is different, we suggest you contact the company for additional help with changing your username or password.

Changing online forums and accounts

Like the Computer Hope forums, most forums allow the user to change their password only through the profile or account settings. However, most companies do not allow you to change your username. Usually, you must create a new account to do this. If you need additional help with changing your username or password on another website, we suggest you contact the company or webmaster in control of that website.

If you are unable to access an online account because you do not know the username or password, look for a link on the account login page for retrieving a forgotten username or password. This option may be able to help in determining what your username or password is or help in resetting your account password.
