Sign with eID

eIDAS-compliant and secure qualified signing.


Sign instantly by using a national eID. Prior registration with primesign is not required.

An existing eID (e.g. German Identity Card or ID Austria/Austrian mobile phone signature) can be used to sign with a primesign certificate. Users only need to authorize the signature by entering their eID credentials. In the background, primesign issues a qualified primesign signing certificate based on the eID. The issued certificate can only be used once for signing.


Which eIDs are supported?

  • German Identity Card (“Online-Ausweis”)
  • ID Austria
  • Handy-Signatur

No eID? No problem! Alternatively, you, your employees, customers, or partners get a personal qualified primesign MOBILE signing certificate issued within minutes and online via remote identification such as video. The certificate can be used immediately for signing, worldwide. Simply use our Onboarding with our voucher codes.

"Sign with eID" can be used in conjunction with our online signing service or primesign SIGNATURE SERVER and is compatible with Adobe Acrobat Sign and Fabasoft products. Our signatures can also be easily integrated into other signature applications via CSC API.
