I haven't used my account in over a year. Do I need to be in-person proofed again?
No, you do not need to be in-person proofed again. The DoD Self-Service Logon credential does not expire. However, if the account is not used for 150 days, the password will expire. To log on to the account again, the password must be reset by answering the challenge questions that were chosen during the initial setup of the account.
