Thank you for reaching out for assistance through the Community! Would you provide which PowerSchool product you are attempting to recover your username and password for, please?
We have an article on How Do I Recover My Username and/or Password, we recommend reviewing the article that should guide you with the steps in recovering the credentials.
We see that you were able to connect with the Unified Talent Applicant Support team and the team was able to send you the recovery email. Please let us know if you are still experiencing an issue logging in.
