ASP.NET MVC 5 Passwords must have at least one non letter or digit

If you are trying to register a new user, and you are getting the error below:

The new ASP.NET MVC 5 web templates are using the Identity framework to do the validation and password policy. This message indicates that the password policy requires a special character. In the event that our password policy does not need such requirements, we can disable this constrain.

To disable this constrain, we can follow these steps:

• Open the identity_config.cs files under the App_start folder
• Search for the string manager.PasswordValidator
• We should see this code snippet:

// Configure validation logic for passwords

manager.PasswordValidator = new PasswordValidator

{

RequiredLength = 6,

RequireNonLetterOrDigit = true,

RequireDigit = true,

RequireLowercase = true,

RequireUppercase = true,

};

• Set the RequireNonLetterOrDigit = false
• Save and compile the application

The password requirements should now be a bit more flexible, and the error should no longer be displayed.

I hope that helps.
