If you’re signing in with a non-migrated Nest Account and you have trouble signing in, you may get a message saying “incorrect email address or password.”
1. Double check that you're signing in with the right email address. Make sure your email address is spelled correctly. If you use multiple email addresses, make sure to use the email that you used to sign up for your account.
2. Double check that you’re signing in with the right password. Your password is case-sensitive, so make sure you use the same capitalization every time.
3. Check the Nest Service status. If there's a service outage, you'll need to wait for service to resume before you can sign in to your account.
4. Reset your password. Select Forgot Password and follow the instructions. You'll receive an email to reset your password.
If you don't get the password reset email, you might have entered the wrong email address. Double check that you entered the email address that you used to sign up for your account.
