The identifier for your Pymetrics account is your email address.
When you are first invited to Pymetrics (by a partner company) you will be prompted to register for an account using the same email address used to trigger the invitation - typically this is the email address used to apply to the respective partner company.
We understand that your main email address may change overtime. For example you may register for an account using a company or school address that you may later not have access to. If you do need to update your account email address or require support to merge accounts, please contact support@pymetrics.com
