Username
Your username is what lets others access your Miwa.lol profile at the URL https://miwa.lol/username (where "username" is replaced by your actual username).
Your username is unique: if someone else has already taken it, you’ll need to choose a different one.
It can only contain letters, numbers, and certain special characters: @, -, ., $, _.
Display name
By default, your display name is the same as your username. You can change your display name independently of your username.
Compared to the username, the display name is not unique and can contain any characters, including emojis. It is displayed on your profile and in the leaderboard.
Alias
This is a Premium feature.
You can set an alias for your username. This is a second username that you can use to access your profile. For example, if your username is miwa, you can set an alias of miwa2. When you do this, your profile will still be accessible at https://miwa.lol/miwa, but https://miwa.lol/miwa2 will redirect to https://miwa.lol/miwa.
