Once a new hero has been created, it can be played immediately without having to provide an email address or entering a password. Only from level 10 you will be asked to validate your account.
If you would like to validate your account earlier, you can do so.
In the game a red exclamation mark next to your avatar reminds you that you have not secured your account yet. In the character settings within the options menu you will also be notified if your character is not yet validated.
To validate a character you need to create an S&F account. If you already own an S&F account you will find a login button below the registration button or in the S&F account settings.
Click the bottom-left gear icon or the red exclamation mark next to your avatar to create an S&F account.
If you have chosen to validate your account with email and password, an email will be sent to the specified email address to complete the validation process. Adding the email addresses firstname.lastname@example.org and email@example.com to your email account's whitelist. This guarantees that our emails are classified as trustworthy and delivered securely. A Google search will usually find instructions on how to whitelist an email address for each provider.
