In late 2012, an estimated 500 million Twitter users sent a staggering 500 million Tweets each day, making the message service one of the fastest growing Internet phenomena of all time. Justin Bieber alone had 37.3 million followers in April 2013, although reports claimed that about half of them were fake. Should Mr Bieber decided to transfer his Twitter to someone else, he would simply need to change his user name, password and registered email address, and hand over control of the account. This process retains the account's followers and other account details.
Open your Twitter account and click the sprocket icon at the top right-hand of the screen. Select "Settings" from the dropdown menu. Choose "Account" from the menu on the right-hand side of the next page.
Write the new user name in the "User name" box and the new owner's email address in the "Email" box. Scroll to the bottom of the page and click "Save changes." You'll be prompted to re-enter your current password to complete the action, then returned to the "Account" page.
Click "Password" from the left-hand menu. Type your password in the "Current password" box then type the new password in the "New password" and "Verify password" boxes.
Give the new owner of the account the revised user name and password and they're ready to start using it.
Once you've surrendered control of your Twitter account, you won't be able to get it back unless the new user consents.
