A lot's been changing over in League of Legends. If it's been a while since you created your account, you'll see new champions, new game modes, and potentially a very confusing new username. If the name you use to log into League of Legends is looking like a garble of letters and numbers, there's a method to the madness.
So why is my Riot Account a bunch of random letters and numbers?
Recently we made the switch from League of Legends accounts to Riot Accounts. As part of that, some accounts needed to change in order to be globally unique (which you can read more about here). In some cases, accounts that were inactive, and had never played a game of League of Legends, had their Riot Account username scrambled into a series of random letters and numbers in order to free up any conflicts with active usernames.
Can I change my Riot Account to something else?
If you want to update your username, you can go to the Riot Account Update page. This page won’t be available forever, though, so make sure you change your name sooner rather than later.
