1. Open your profile, and click the “Edit Profile” button
2. Click on your bio to edit
3. Update your bio by adding any profile usernames (using “@”) or hashtags (using “#”)
4. Click “Done”

It’s as easy as that! Now your username mentions and hashtags will be clickable links within your Instagram bio.

Generally speaking, it’s a great thing to have your username linked on someone else’s bio, because it adds more visibility to your account and allows their followers to discover you. This is simply a security measure to keep accounts from abusing the new feature.
