# Set Nickname
When setting the nickname, it is **available if it is a blue background** and **not available if it is a red background**. If you select a nickname with a blue background, your wallet and nickname will be successfully registered. At this point, you can see that your wallet is logged in at the top right, and you can **click on your account to choose which service you want to use**.
**Blue Background: Nickname Available**
**Red Background: Nickname not available**
**Choose the service from the top-right**
