email address help.

hello. recently my main email address forced me to enter a new password for security reasons and i didnt write down the new password i entered and i screwed up and forgot the pass.Normally i wouldnt mind that much but this is my main account and i dont feel comfortable knowing i cant access the email address linked to it. is there any way we could change the email address? if i need to contact riot support i have to use my 2nd email address and explained what happened? anyway thanks for help.
