You will be redirected to the external authentication provider during this process. If you havent used this login before, you are likely to be prompted by the provider to login. Afterwards, the external authentication provider asks you for your permission to share your data (name, gender, confirmed email address). If you grant access, an account in our store will be created based on this information. If you are a returning customer and logged in using an external authentication provider, youll be asked to log in to that provider again.
