In general, no.
Whether you verify your identity by yourself (by uploading acceptable identity documents) or with the help of a Trusted Referee, your Verified Identity becomes part of your ID.me account.
The next time you sign in to the partner website (for example, a state workforce agency, VA.gov, etc.), just provide your ID.me Email address and Password, as well as the multi-factor authentication method you set up previously. (You may be asked to complete a one-time step to Allow the partner to access your identity information.)
No further identity verification is required.
NOTE: Some partners may occasionally choose to increase security measures, and additional documentation or a 'video selfie' may be required.
