Auth0 email validation policy

Hey everyone,

I’ve been searching for Auth0’s email validation policy, an official regex that is used or any other kind of specification/instruction.

I’ve gone through the following posts on the forum:

  1. Email validation rules, please make them public knowledge - #6 by jesse2
  2. Email regex verification
  3. Email validation for Auth0

All three posts are at least 6 months old, the third one being the latest, dating from January this year.

Has there been any official updates on Auth0’s policy about this?


Hi @dusan.p.petrovic,

Thanks for reaching out to the Auth0 Community!

AFAIK, there have not been any further official updates on the email validation policy. It looks like the first link you shared is the corresponding code snippet that performs the email validation behind the scenes to determine if the email address is valid.

Please reach out if you have any additional questions.
