An X (formerly Twitter) bio is part of setting up your X profile. It appears below your name and X handle on your profile. Use it to give others a brief introduction to who you are, list your interests, or promote your business.

You can change your X bio by editing your profile. You can also optimize it with hashtags and @usernames.

Select your photo or image at the top of your X homepage.

The Edit Profile window will open. Scroll down to the Bio field and enter your bio. Select Save at the top of the window to apply the changes.
