tymsb (tymsb) asked a question.

Email property - email prefix and domain advised limits?

Hi community,

As per Okta documentation, 'email' property should be within 5 to 100 characters. And we are also setting up the domain whitelisting in our app. Therefore, I have the following questions:

  1. Advised limit to the email prefix?
  2. Advised limit to the domain name?
  3. Does Okta accept sub-domains?

Thank you

    Hi, @tymsb (tymsb)​ 

     

    Thank you for posting on our Community page!

     

    I have done some research and found this article which better explains supported email attributes

     

    Additionally, you can also take a look on this article on custom domains:

     

    In short, the limit of 100 characters applies to the entire email address, including subdomains. There is no specific limit for each attribute except top-level domains (the 'com' portion of the email address) which range from min 2 to max 20 characters.

     

    Hope this helps!

     

    Thank you for reaching out to our Community and have a great day!
