I have forgotten my password
Use Forgot password? on the sign in page. Enter your email address and we send you a link to set a new one.
The page always says to check your email, whatever you type. That is deliberate, so nobody can use it to find out who has an account. A reset email only goes to accounts that were created with a password.
If you only ever signed in with Google, no email will arrive. Go back to the sign in page and use Continue with Google instead.
Still need help? Email info@proactivly.app and tell us the email address you are trying to sign in with. If you are on a program, your coach can help too.
