Hi Team,

I would like to allow some special characters in username and email of identity user.

Can you please guide me how can I achieve this.

Currently I'm getting this error "Username 'pankaj.bhasin-O'mail@initto.ca' is invalid, can only contain letters or digits." (this is the test email sample and error which I'm getting, I would like to allow -' and other special characters in UserName and Email)

Thanks

    Hi,

    You can try:

    Configure<IdentityOptions>(options=>
{
    options.User.AllowedUserNameCharacters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@'+";
});
