Changing your email ID and password is now possible through your Arm Account profile.
I can't find how to change the email address used to login. Is it possible ?
Hi Myy (myy)
Thanks for bringing this up. It isn't possible to do this independently right now so I'll turn this into an idea and track its progress to enable this.
To solve this for you now, please email community.arm.com the address you'd like to change it to. I'll make the change, then you'll need to use the 'Sign up now or re-activate your existing account' link on the log in screen to link the accounts.
