Four things happen on every strongly verified signature. None of them require a certificate to be issued for the signer.
Signer authenticates via 2FA, an authenticator app included at no extra cost, or SMS OTP as a paid add-on
Each signer is uniquely identified via a reference ID, binding the signature to one person
The document is hashed and sealed with a trusted timestamp, so any change after signing is detectable
Everything lands in the same tamper-evident audit trail and compliance certificate as every other Asignu signature
Most platforms issue a certificate per signer, per signature. That cost is real, so they meter it and charge you for every strongly verified signature you send.
Asignu combines signer authentication, unique transaction evidence and PAdES sealing with a trusted timestamp - no per-signer certificate. Signing stays part of your per-user price instead of being metered per document.
If a document legally requires the highest standard, use QES. Everything else runs on standard signing with strong signer verification.
Read about QES →eIDAS defines three levels. You choose per document, in the same flow.
Simple Electronic Signature
A secure link, optionally confirmed by email OTP. Fastest to complete, lowest friction for the signer.
Advanced Electronic Signature
Authentication through 2FA or SMS OTP, unique signer binding and tamper-evident sealing designed around eIDAS Article 26 requirements.
Qualified Electronic Signature
The same legal effect as a handwritten signature across the EU, through government-backed identity verification.
