Username Tips: Pick, Check and Protect

A good username is short, easy to say out loud and free on the sites you care about. Finding one that meets all three is harder than it sounds, because the obvious names went years ago and every platform has its own rules about length, dots, underscores and how often you can change your mind.

This section collects the practical side of picking and keeping a handle. You will find advice on coming up with a name that is unique without being unreadable, a step-by-step method for checking whether it is taken across many sites at once, and help for the opposite problem: you made an account years ago and cannot remember what you called yourself.

For businesses and creators, there are guides on claiming your brand name before launch, spotting lookalike accounts, and setting up the access rules that stop a handle from walking out the door with a former employee. We also compare the free availability checkers so you can pick the one that fits.

The main advice is the same everywhere: check widely, claim the name on every platform you might use in one sitting, and confirm on the signup form itself, because an automated "Not found" is a strong hint, not a guarantee. Our free search covers the handle check and also shows whether the matching .com, .net, .org, .io, .us, .app or .dev domain is open.
