[2021] I need help with steam

Hey there. If you want to use a current OSRS account you have to make sure it's linked to that specific account. An account in OSRS will be automatically be linked to RS3. Unfortunately at this time you can't switch between accounts.

First step is make sure your Steam is definitely not linked (I assume you've done this step) - https://support.runescape.com/hc/en-gb/articles/360013578958

If you can't remember your email for RS3 you'll have to reset it. You might find this useful - https://support.runescape.com/hc/en-gb/articles/207555905

Then link to your OSRS account - https://support.runescape.com/hc/en-gb/articles/360013472017

I realize you don't like the articles so I apologise for sending 3 across to you, but most of the information is there.

Thank you for supporting our launch on Steam and hope you can enjoy OSRS on Steam very soon.

Ah that's super unfortunate. Unfortunately if your steam email is lost then that's a whole separate issue.

You can still recover it through Steam, though, but it just might take more time.
