Signing a document without an account: the Sign-Hub journey
Upload a PDF, enter the signer's email, receive a link: Sign-Hub lets you get a document signed online without the signer having to create an account. Comparison with La Poste's electronic registered mail.
In brief: Sign-Hub lets you get a document signed online in just a few minutes, without the signer needing to install any software or create an account. This journey, often compared to electronic registered mail, provides a timestamped and verifiable proof, but with important differences to be aware of.
The need: getting a contract signed within the hour
You are a consultant, a craftsman, or an SME manager. A client sends you a quote or a contract to sign quickly. You don't have an integrated signature platform, no account with a provider, and the client doesn't have any particular tool either. You simply want them to sign, without having to create an account or install an application.
The Sign-Hub service addresses this specific case. Here is the actual journey, from uploading the PDF to retrieving the signed document.
The Sign-Hub journey, step by step
- Upload your PDF to the platform (or via the API, but the web interface is enough).
- Enter the signer's email address and, if needed, their name.
- Sign-Hub sends an email containing a personal and secure link.
- The signer opens the link: they see the document, can read it online, ticks an explicit consent box, then receives a code by email which they enter to validate their identity.
- They sign with their mouse, their finger on mobile, or by typing their name.
- You receive a notification (webhook if you use the API) and can download the signed PDF and a proof file.
The signer has nothing to install and creates no account: they receive a link, they click, they sign. This is what is called a simple electronic signature within the meaning of the eIDAS regulation (Regulation (EU) No 910/2014), reinforced by email verification and document sealing.
What the proof is worth with Sign-Hub
The value of an electronic signature rests on the proof it leaves behind. Sign-Hub provides several elements:
- Explicit consent: the checkbox and the entry of the code are recorded in a log.
- Frozen document fingerprint: the signed PDF is sealed in PAdES format (PDF signature standard); any subsequent modification of the file is detectable.
- Optional timestamping: you can enable RFC 3161 timestamping with a third-party authority, which anchors the date and time reliably.
- Independently verifiable proof file: the file is signed with an Ed25519 key whose public key is published on the Sign-Hub website. Anyone can verify the
proof.jsonfile offline or via the online verification page. This transparency is rare: most players require you to trust their platform.
In the event of a dispute, these elements make it possible to demonstrate that the document was indeed signed by the person with access to the email address, at a given moment. But you need to be aware of the limitations.
Comparison with La Poste's electronic registered mail
Electronic registered mail (AR24, a La Poste service) is often cited as a reference for sending documents with reinforced probative value. Here is a factual comparison.
| Criterion | Sign-Hub | La Poste electronic registered mail (AR24) |
|---------|----------|------------------------------------------|
| Nature of the proof | Reinforced simple eIDAS signature (email + PAdES sealing) | Electronic registered mail: proof of deposit and distribution, with specific legal value (Article L.100 of the French Postal and Electronic Communications Code) |
| Signer identification | By email (code sent to the address) | By email or SMS, sometimes with reinforced identity verification (depending on the option) |
| Document signed? | Yes, the document is electronically signed | No, electronic registered mail does not sign the document; it attests to sending and receipt |
| Legal value | Proof of consent and document integrity | Proof of notification (date and time of availability) |
| Independent verification | Yes, public key published | No, you have to trust the AR24 service |
| Price | Per act, no subscription (e.g. Pack of 25 acts at €12.50) | Varies by volume, often with a subscription |
What is equivalent: in both cases, you get a timestamped proof of sending and receipt of the document. The recipient does not need an account: they receive a link and act online.
What is not equivalent: La Poste's electronic registered mail aims to prove that you notified a document (for example, a formal notice). It does not count as a signature of the content. Sign-Hub, on the other hand, collects the signature of the document: the signer expresses their agreement with the content. These are two complementary uses.
What the proof is worth: on the Sign-Hub side, the proof is technical (cryptographic) and verifiable by a third party. On the La Poste side, the proof is legal but relies on the operator's authority. In the event of a dispute, a judge will assess the elements. For signing a contract, proof of consent is essential; for a notification, proof of distribution is.
The limitations to be aware of
Sign-Hub offers a simple signature within the meaning of eIDAS: it does not benefit from the legal presumptions of advanced or qualified signatures. This means that in the event of a challenge, the burden of proof falls on you (you must demonstrate that the signer is indeed the person who signed). Email verification is an identification factor, but it is not infallible.
The service is available in mainland France and in the overseas departments and regions. Data is hosted in the European Union, and Sign-Hub anonymises connection data in accordance with the GDPR, without breaking the proof.
How to get a document signed without an account: instructions
- Go to Sign-Hub and create an account (it's free for the Discovery offer, 10 acts per month).
- Click on "New request" and upload your PDF.
- Enter the signer's email. You can also enable automatic reminders (paid option).
- Send the request. The signer receives an email with a link.
- Track the status in real time. As soon as the document is signed, you are notified.
- Download the signed PDF and the proof file. Keep them safe.
In brief: Sign-Hub lets you get a document signed online without the signer having to create an account or install software. The journey is simple and fast, the proof is technical and verifiable. For uses where notification takes precedence over signature, La Poste's electronic registered mail remains an alternative. But to collect agreement on a contract, Sign-Hub's electronic signature is suitable, provided you understand its level of proof.
