Qualified One-Time Electronic Signature
A qualified one-time electronic signature is the perfect solution for businesses that need to sign a single document quickly and legally, without investing in annual certificates.
What are qualified one-time electronic signatures?
Qualified one-time electronic signatures are a modern form of digital signing that combines convenience, speed, and full legal compliance. They allow you to sign a single document online without the need to invest in a long-term certificate or go through complex procedures.
In terms of legal effect, a one-time signature has the same power as a traditional qualified electronic signature. The key difference lies in the simplified process — identity verification and certificate issuance happen within minutes, keeping formalities to a minimum.
This solution is especially valued in situations where a document needs to be signed quickly and just once — with no long-term commitments.
In what situations is a qualified one-time electronic signature useful?
Occasional Signatures
For companies whose employees or contractors occasionally sign important legal documents, contracts, or official applications — without the need to purchase a long-term certificate.
Remote Work
For employees working outside the company’s office who need to handle formal matters in an official and legally valid way.
Remote Contract Signing
For job candidates — both local and international — who sign employment contracts remotely.
High-Volume Recruitment
For organizations running large-scale recruitment processes, where collecting signed documents from multiple candidates needs to be fast and efficient.
Partner Collaboration
For companies with a network of distributors or business partners who regularly sign or update documents.
One-Time Clients
For businesses serving clients who need to sign a document only once — such as a consent form, declaration, or single-use agreement.

Frequently Asked Questions about the Qualified One-Time Electronic Signature
1 When might a qualified one-time electronic signature be needed?
A qualified one-time electronic signature may be needed when an electronic document must be signed in a way that is legally equivalent to a handwritten signature — for example, in the case of contracts, powers of attorney, or formal declarations.
Such situations often involve employees or contractors who need to sign a document only once and do not require a permanent certificate. In these cases, a qualified one-time certificate is a convenient alternative — fast, remote, and fully compliant with legal regulations.
The entire process is completed online in just a few minutes. Identity verification takes place remotely — either through a short video call with an operator or independently using the Nect mobile app.
2 How long is a qualified one-time electronic signature valid?
A qualified one-time electronic signature is based on a certificate that is active for 20 minutes from the moment it is generated. During this time, it can be used to sign only one document as part of a specific signing process.
The certificate is automatically applied by the system within 1–2 minutes, and once used, it cannot be reused. This solution is designed specifically for one-time, formal signing actions.
3 How does identity verification work for a qualified one-time electronic signature?
Identity verification before applying a qualified one-time electronic signature involves just a few simple steps.
After clicking the link, the user selects one of two available methods:
- Video verification with an operator – a short online call, lasting around 2–3 minutes, during which the operator confirms the user’s identity.
- Self-verification via the Nect app – the user receives an activation link via QR code or SMS. They then take a photo of their ID document and a selfie, following the app’s on-screen instructions.
Once verification is successfully completed, the user gains access to the certificate and can proceed with signing the document.
The entire process typically takes between 5 to 10 minutes.
4 In which languages can identity verification be conducted?
The identity verification process for a qualified one-time electronic signature is available in several languages, depending on the chosen method.
Video verification with an operator is available in:
- Polish
- English
- Ukrainian
- Russian
- German
Self-verification via the Nect app supports:
- Polish
- English

5 What is needed for identity verification?

6 Are there any limitations to using a qualified one-time electronic signature?
Yes, there are a few important limitations to keep in mind when using a qualified one-time electronic signature:
- A one-time certificate allows you to sign only one document — it cannot be reused.
- The signature works exclusively within the AMODIT Trust Center platform, where it was generated.
- Not all documents can be signed electronically — some legal actions require specific forms. Always check if electronic signatures are accepted for your specific case.
- The ID document used must be valid and in good condition — all data must be clearly visible, and the document must not be damaged.
