Facebook only allows you to change your username once every few months, and the name you choose must be at least a reflection of your real legal name, though common sobriquets are acceptable.
Twitter, on the other hand, has no such limitations in place when it comes to usernames.
You can change your Twitter username daily if you so choose, and it can be anything you want, from a take on your own real name to an ironic play on a celebrity to a collection of random numbers and letters.
Changing your Twitter name can allow you to become more anonymous online, to choose a title that will be more readily found in searches, or simply to reflect your current mood.
And as changing a Twitter username takes about a minute and most, there’s no reason not to change it from time to time. Just note that changing your username will not change your display name, which is the name that displays under your profile picture on your home Twitter page and beside your avatar on your Tweets. (Changing that name, which is not as useful for search, both within Twitter and via search engines generally, is also quite easy, though it’s a story for another day.)
Note, however, that if you have a verified Twitter account, changing your Twitter username will result in the loss of your verification badge at your current handle.
How to change your Twitter username
1. Log into your Twitter account.
2. Click on your Twitter avatar at the top right corner of your computer (top left for mobile), then hit “Settings and privacy” on the menu that pops up.
3. In the box by the word “Username,” simply type in the new username you’d like to use. If available, green lettering will appear reading “Available.”
4. Click the “Save” box at the bottom of the screen.
And that’s that.
