Can you revert to your old username after changing it?

Yes, on Twitter, you can revert to your old username after changing it. However, there are a few important considerations and limitations to keep in mind:

1. **Time Limit:** You can revert to your old username within 30 days of making the change. After this period, the old username may become available for others to register.

2. **Availability:** Your old username may not be immediately available for re-registration if someone else has already taken it during the 30-day period.

3. **Username Change Limit:** Twitter imposes limits on how frequently you can change your username. Generally, you can change it every 30 days.

### Steps to Revert to Your Old Username:

1. **Access Account Settings:** Log in to your Twitter account and go to your account settings.

2. **Edit Username:** Navigate to the username section in your settings and click on it to edit.

3. **Enter Old Username:** If your old username is still available (not taken by someone else), you can enter it again.

4. **Save Changes:** Click on the "Save changes" button to revert to your old username.

### Considerations:

- **Profile Updates:** After reverting to your old username, remember to update any external links or profiles that may reference your previous username.

- **Impact on Mentions:** Reverting to your old username will update your profile and mentions on Twitter. However, previous mentions of your new username will not automatically update to your old username.

- **Account Security:** Ensure that you are logged into the correct account when making any changes to your username to prevent unauthorized modifications.

By following these steps and considering these factors, you can revert to your old username on Twitter within the allowed timeframe and maintain consistency in your online identity.
