When you sign up for a group or solo subscription, a critical part of the process is to enter your email address. This is used to allow you to sign into your account as well as to reset your password in the event that you are locked out of your account.
If you've entered the wrong email address and want to correct this issue, you can easily do it by changing the email address on your account. To do this, go to https://onsongapp.com/account and sign in with the email address you had entered and your password. You should already be signed in unless you have opted to sign out. You can then tap on Profile on the left to view your personal user profile at https://onsongapp.com/account/profile Here's where you can change the email address. Type in a new email address and save changes. You should now be able to sign in using that email address next time you access your account.
