Consigne

I cannot get the signature to work

The code never arrives, the link expired, the document will not open: what to do in each case.

Updated on 13/08/2026

Almost every problem when signing is one of these four, and all four are fixable without calling anyone.

What happensWhyWhat to do
The code never arrivesPoor signal, or the number is not yoursRequest another code. If that fails too, tell the sender: they may hold the wrong number
The link has expiredLinks have a deadlineAsk the sender for a new one. It is immediate
The document will not openSlow connection or a very old browserTry another browser, or mobile data
I lost the emailUsually in spamSearch for the sender's name; failing that, ask them to resend

Worth knowing

Requesting another code invalidates nothing: the document is still waiting, and signing it a day later is worth exactly the same.

What not to do

  • Sign on someone else's behalf, even if asked. The signature states who you are, and that is precisely its value.
  • Forward your link to a colleague so they can sign for you. Let them sign with their own.
  • Print, sign by hand and scan it back, unless asked to: it loses the evidence.
How many times can I request the code?

As many as you need, with a few seconds between attempts.

Can I sign without a phone?

It depends what the sender required. If they require a phone code, you need one.

What if the document has an error?

Do not sign it. Speak up: correcting and resending is faster than voiding a signature.
