Guide
Getting the most from the username generator
Short, readable, consistent
Good usernames are easy to say out loud and to type. Use the same handle across your profiles where you can, so people find you.
Avoid confusing characters
Dots, dashes and underscores are allowed on Ontu, but too many make a name hard to share. Numbers can look like spam unless they mean something.
We only check Ontu
Availability shown here is for Ontu only. Check other platforms yourself before you commit to a name.
