Certification validity and company email

Hi all,

I have a few questions.
I am certified under my current company e.g. gotten access into partner portal and certified via my current company with my company email address.

I will like to check, what is going to be like when i leave my current company.
Am i able to retain my certification and change it certification tie to myself, maybe by changing the email to my personal email, or all my certification will tie to my current company?

Thank You
