No, it's not possible to take the HIGH5 test without an email address. An email address is required for account creation. Registering with an email address ensures that your results are securely stored and accessible to you whenever needed. Having an email address also allows us to provide you with personalized updates and support regarding your strengths journey.
If you don't want to register via email address, you can also register with your LinkedIn or Google account. However, both of them require an email address to create an account.
