How to get a qualified electronic signature online in 15 minutes – step by step

Modern technologies allow significant acceleration of many business processes. In this context, the qualified electronic signature deserves special attention. In the past, signing documents required an in-person visit to an office, which involved not only spending time but also additional logistical costs. Today, the entire process can be carried out remotely. Thanks to this, entrepreneurs can obtain a legally binding electronic signature within minutes, ready for immediate use in daily business activities.

Our step-by-step guide on how to get a qualified electronic signature online in 15 minutes is based on a simple process. The first step is to create a free account on the SIGNIUS Professional platform. Next, you purchase a selected package of qualified signatures and complete a one-time identity verification. The whole process takes only a few minutes, and after completing it, you can immediately start signing documents electronically. A convenient solution for companies and individual users is the ability to purchase signature vouchers in the online store. These vouchers allow you to flexibly adjust the number of signatures to current business needs—from single transactions to regular document workflows. The offer includes vouchers for 5, 10, 30, 120, 600, and 1200 qualified signatures, which allows easy access management across teams and full cost control.

The verification process is extremely simple and fast. It is carried out via selfie identification — no appointment required. Once your identity is confirmed, you receive qualified signatures instantly and can start signing documents right away. The entire process is fully compliant with legal requirements and the eIDAS regulation, ensuring the highest level of security.

Qualified signature: what’s worth knowing?

What is a qualified signature and what is it based on?

A qualified electronic signature is an advanced form of electronic signature with the same legal force as a handwritten signature. It operates under the eIDAS regulation, applicable throughout the European Union. It is issued by a qualified trust service provider (QTSP), ensuring legality and security. Documents signed this way are recognized in all EU countries, greatly facilitating international business operations.

Can you get a qualified signature on SIGNIUS in 15 minutes, and who issues the certificate?

Yes, on the SIGNIUS platform you can obtain a qualified signature in just 15 minutes, with the entire process completed 100% online. The qualified certificate is issued by EuroCert, a certified Qualified Trust Service Provider (QTSP). Thanks to cooperation with a reputable provider, you can be sure that your signature meets all legal requirements and is accepted by public institutions and business partners.

What documents and equipment are needed to obtain the signature quickly?

You do not need additional devices such as card readers or cryptographic cards — everything is done online, which greatly simplifies the process and lowers costs. To obtain a qualified signature, you need:

• a valid ID card or passport,

• stable internet connection,

• a device with a camera and microphone (computer, laptop, or smartphone),

• an email address,

• a mobile phone for SMS authentication.

Do you need to create an account on the platform?

Yes. To use a qualified electronic signature, you must create an account on the SIGNIUS Professional platform. This is a security requirement that allows the provider to verify your identity and assign the certificate to a specific user. The registration process is simple and takes only a few minutes. After creating your account, you gain access to the user panel where you can manage your documents and signatures.

Is a card and reader necessary, or is internet access enough?

With SIGNIUS, you do not need any cards or readers. We offer a fully online qualified electronic signature, meaning all data is stored on secure servers, and you can access it from any device with internet access. This is a much more convenient solution that eliminates the risk of losing a cryptographic card and does not require installing additional software.

What are the remote verification hours?

Remote identity verification is available through the mobile app as self-identification, accessible 24/7 except on holidays. This helps you save the time you would otherwise spend visiting a physical service point. The procedure is secure and compliant with legal requirements, and user identity is confirmed in real time. Once verification is complete, the qualified certificate is activated immediately, allowing you to start using your qualified electronic signature for signing contracts, submitting applications, or handling corporate documents.

What are the limits and file formats on the platform?

By default, the SIGNIUS platform allows signing documents up to 10 MB in size. For business accounts, this limit can be increased. The platform supports PDF files, the standard format for business and official documents. The system is optimized for performance, so even signing multiple documents at once is smooth and fast.

Can you invite multiple signers and set signing order?

Yes, the SIGNIUS platform allows inviting multiple signers and specifying the order in which they should sign. This is highly useful for multi-party agreements or documents requiring approval from several individuals. Each signer receives an email notification with a link to the document awaiting signature, streamlining the entire workflow.
