How often can you change your Twitter username?

On Twitter, you can change your username (also known as your handle) as often as you'd like. There are no specific restrictions on the frequency of changing your handle, so you can update it whenever you wish. However, it's a good idea to choose a handle that you'll be comfortable with for a while, as frequent changes might confuse your followers or affect how people find you on the platform. Just keep in mind that changing your username will also change the URL for your profile.
