Hi,

Our Signature column allows you to electronically sign one or more column values in your form. Use it for approvals or in any scenario that requires tight control over the changes in specific columns. Whenever one of the signed column values is changed by anyone, the signature is automatically broken and, because it's a column, you can display the signature in any list view or form.

Our on-premises signature has always supported the ability to sign using your user name and password. It's especially important in cases where various regulatory compliances are required, such as 21 CFR Part 11. The user is required to enter their user name and password and only then is the signature added to the item. We also support various other signature types, such as hand-written signature, declarative signature and even USB signature pads.

Until now, we did not support user name + password signatures in our Office 365 version. You can add a hand-written signature and even display that signature in print-outs, but you could not build compliant solutions.

We now released support for these types of signatures in Office 365 as well! When you choose this signature provider, you will see a button labelled Sign. Click on this button and a pop-up window opens. This is the standard Microsoft Azure Active Directory authentication window you use to log into various Azure services, such as your SharePoint Online. Enter your credentials and the window closes, now the button's label has changed to Clear, allowing you to delete the signature. 

Once the item is saved, the signature is validated again on the server side, preventing any falsification attempts and the item is signed. As with any signature type, any change to one of the signed fields automatically breaks the signature. The new signature type is supported both in Classic forms and in the form created in our brand-new Form Designer!

NOTE: if you are using IE/Edge and have added your SharePoint URL to Trusted Sites, please add https://login.windows.net there as well, it will ensure the two windows can communicate.
