How we picked the 7 top rated products

We chose the high-performing solutions on this list based on verified user ratings on our site. Depending on available data, qualifying products either had to be among the most user-reviewed or the most searched-for products in the Digital Signature software category. They also needed to have sufficient reviews about authentication, have a minimum user rating of 3 out of 5 for that feature, and show evidence of U.S. market presence. We then added a distinction for up to three products based on our proprietary ratings and reviews: Highest rated, Highly rated for authentication, and Highly rated for free version. Sponsorship or client status has no influence on the selection of these products, but it may impact the order in which products appear.

“I appreciate having the authentication option available per document using either SMS or PIN. There's one small drawback when inputting the verification code on iOS. The keyboard comes up as the regular QWERTY keyboard instead of the number pad (which would be ideal), and it kept reverting from the number/symbol alternates back to the letters after I typed in each code digit.”
