Digital Signatures & Seals
Sign locally using the signing token
Use our USB token to sign locally, encrypt emails, or authenticate yourself. You can also choose to use a smart card instead.
Everything you need to know about the USB token
eIDAS Certified
Our solution is eIDAS-certified for qualified electronic signatures (QES) that are legally binding and recognized across Europe.
Very user-friendly
Simply plug the token (USB-C or USB-A) into your laptop’s USB port. No additional hardware like card readers is needed for local signing.
Easy to use in various scenarios
Compact and portable, the USB token is easy to carry and can be used on different devices.
High level of security
USB tokens add a layer of physical security and ensure that digital signatures, seals, and confidential documents remain protected from unauthorized access.
The signing token allows you to do more than just sign locally
Authentication (auth token)
Auth tokens, or authentication tokens, are digital keys or codes used to confirm the identity of a user or system. These tokens are often generated after a successful login or authentication and are then used to maintain the user’s identity during a session or when accessing protected resources.
Signing and Sealing (singing token)
Sign tokens enable clear verification of the origin and integrity of data. By using cryptographic methods, documents can be securely signed and sealed locally – reliably, traceably, and in compliance with legal standards.
Email Signature (mail signing token)
Mail Sign Tokens enable encryption and signing of emails directly at the time of sending. This ensures that confidential information remains protected and the integrity of the content is always verifiable.
