3. Avoid “Continue with Google” Issues for Corporate Accounts

If you are using the “Continue with Google” option to log in, there may be complications if:

• Solution: Instead of using Google sign-in, manually enter your Avast account email and password. Avast Support
• If you still want to use Google login, switch to a personal Google account that’s linked to your Avast account. Avast Support

4. Wait If Avast Servers Are Down

Sometimes, login errors happen simply because Avast’s servers are temporarily down for maintenance or experiencing issues.
