What is an Electronic Certificate (Public Personal Authentication Service)?

The Public Personal Authentication Service provides a secure and reliable way for individuals to prove their identity online. Electronic certificates, also known as digital certificates or public key certificates, are digital credentials that bind a public key to an individual’s verified identity. They are crucial for accessing various online services, including e-government portals, tax filing systems, and other official administrative procedures.

Key Information: Validity Period of Your Electronic Certificate

Why is Knowing Your Certificate’s Validity Period Important?

Understanding the expiration date of your electronic certificate is vital for several reasons:

  • Continued Access to Services: Many online government services require a valid electronic certificate for authentication. If your certificate expires, you may be unable to access these services until you renew it.
  • Proactive Renewal: By being aware of the expiration date, you can proactively initiate the renewal process well in advance. This prevents any disruption to your ability to conduct official business online.
  • Security: While the technology itself is highly secure, it is good practice to keep your digital credentials up-to-date.

What to Do When Your Certificate is Nearing Expiration:

Sagamihara City encourages residents to check the expiration date of their electronic certificate periodically. Information on how to check the validity period and the renewal process can typically be found through the service provider or by contacting the relevant Sagamihara City department responsible for public personal authentication.
