Signer Authentication and Security. Two-Factor Authentication

Has anyone attempted to steal your online information lately? We understand that while many of you like the convenience of logging in to your online accounts with a single click, others are more interested in enhanced security options. In order to help prevent phishing for your login credentials, pdfFiller is one of the first document management services to develop an account login with two-factor authentication.

If you go to our login page, you’ll notice that there are now four different login options available. The first is the traditional email and password combination. Remember that if you click on the checkbox next to ‘Remember Me’ and close pdfFiller without logging out, the next time you open pdfFiller, you will be taken directly into your Medics page. There is also an option to retrieve your password here using an email or phone number. For those of you for whom security is a priority, pdfFiller also allows you to log in with your phone number. This recently added option, available to those who have a phone number saved in their account information, requires a two-factor authentication process, similar to what you may have encountered when dealing with your online bank accounts. Simply click the ‘Login with Your Phone’ button, and you’ll be taken to a page where you can enter a phone number. After clicking ‘Send Pin’ you’ll receive a code via SMS. Enter this code and click ‘Log in’ and you’ll be taken directly to your Medics page. This method, which requires two keys for account entry, helps prevent phishing and makes it much more difficult for a stranger to access your personal information.

Very easy to use That I could fill it in immediately and be able to upload it and save it somewhere else. Also that the formatting remained the same That I had to save it twice in order to get what I had wrote. I also hate that the text box does not stay within the area you type in.

Digital signatures use the PKI standard and the Pretty Good Privacy (PGP) encryption program. Both reduce potential security issues that come with transmitting public keys. They validate that the sender's public key belongs to that individual and verify the sender's identity.
Our service is secure, and your documents are safe on our servers. Only you and the people you invite to sign have access to your documents. The communication with our service is 100% encrypted.
5 Steps for Validating Digital Signatures In a PDF Open the digitally signed PDF that you need to validate using Power PDF. Locate the digital signature object within the document. Right click or command-click on the signature object. Select "Verify Signature" from the context menu.
Yes, all the signatures you create with our service are legally binding and are recognized in court. DigiSigner is compliant with all major eSignature laws, including ESIGN, UETA, and European eIDAS.
While digital signatures offer many benefits, several risks are associated with their use. Some of the most pertinent risks to be aware of include: Forgery and Identity Theft: Cybercriminals can steal private trusted keys and execute signatures on documents not intended to be signed.
A digital signature confirms that any macros, code modules, and other executable components in the database originated with the signer and that no one has altered them since the database was signed. This helps people who use the database decide whether to trust it and its content.
