SigninID, a service from Peerborough, Inc., helps people protect their personal and business email addresses when signing up for websites and online services. Rather than using a work inbox for external registrations, users can create a SigninID email address and keep sign-up messages separate from important business correspondence. The service is designed to reduce exposure of sensitive email accounts and make incoming messages easier to manage.

SigninID supports secure access to security codes, requiring authentication through a fingerprint, face scan, PIN, or device pattern before access is granted. Its passkey features are intended to make sign-in more convenient while helping protect accounts from guessed or reused passwords; biometric information remains on the user’s device. The service also offers account transfers by updating access permissions, helping maintain continuity when responsibilities change.

SigninID uses Amazon Simple Email Service to receive messages. Its listed Pro plan includes one user, a secure sign-in email address, unlimited sensitive messages and security logs, up to 100 aliases, email forwarding, email support, and an ad-free experience.
