With the introduction of MitID, there is a new signature type that is designed as a replacement for NemID in 2023:

MitID provides three assurance levels:
- Low, Substantial, and High.
- Contractbook signature currently comes with a Substantial assurance level.
You will automatically get an assurance level along with your MitID.
Your assurance level and MitID authenticator determine precisely what you can log on to and approve with MitID.
If you need to sign a contract using private or business MitID, you will be redirected to the following login page:

After you have authorized your MitID user by ID, CPR and password, you can complete the signature in Contractbook.

The default signature type for all Contractbook drafts is one of the advanced signatures - SMS Verification.
If you save one of your templates as a draft, the standard signature type will be automatically set to an SMS verification.
It is impossible to control the default signature type on a template level.
If you want to change the signature type for your contract, you need to do that in its draft mode.

Now you are ready to send the contract to all recipients and sign yourself if you are one of the Signees.

To get to this final step, after you have chosen the signature method and type, you can click Send and sign if you are one of the signees.
- Below is an example of using one of our most commonly chosen signature types, "Sign with a click."
- You will be invited to confirm the signature by "long-pressing" the green confirmation button:

If you have chosen that only others will sign the contract, you can click a green button called Send for signatures.
And if you are the only one signing, the button will be named Sign - when completed, your contract will transition from pending to signed.

As a Recipient, you can select the signature type you prefer from a multiple-choice list the Sender has provided you with or sign with the specific signature type they have selected for you.
You can also Request changes in the contract sent to you if you want to replace the default requested signature type on the document.
- Below is an example of completing the "Draw a signature" as a contract recipient.
- You can choose to save the hand-drawn signature for the future and use it next time you are signing with the same method in Contractbook:

If you are not representing the only and last required in the contract signatures, be aware that the flow will look different than above, as the contract will remain Pending.
Below is this example when completing the signature with "SMS verification code," which is Contractbook default signature type:
