As a new small business operator, this software has helped me with so many tasks without having to leave work. The only draw back is that many times, recipients can't open sent pdf files and another route has to be taken.

I like everything except when filing in…
I like everything except when filing in the forms the lines do not automatically wrap to the next line. I have to know to stop and manually go to the next line, Maybe that could be fixed. Also, when I tried to share the completed to form via email; nothing was received by the recipient. Only via fax did information get received.

The PDF Filler worked great
The PDF Filler worked great. I only used it once and since I had no occasion to use it again, I cancelled. There were no issues with the cancellation. The charge was removed from my credit card. I am very happy with this product. I will order it again when I need it.

How do you authenticate?
The first trick is to go into your phone's main Settings menu and then Accounts & sync and simply remove the Google account that is getting the “authentication is required” error. Once you've done this, you can re-add the account, and it should work just fine.
What is the best way to authenticate users?
Passwords. One of the most widespread and well-known methods of authentication are passwords.
Two-Factor Authentication.
Captcha Test.
Biometric Authentication.
Authentication and Machine Learning.
Public and Private Key-pairs.
The Bottom Line.
How do I authenticate a user?
Manage the connection between the human (user) and the website's server (computer).
Verify users' identities.
Approve (or decline) the authentication, so the system can move to authorizing the user.
What is the best way to strengthen user authentication?
Don't Go All or Nothing.
Use the Authentication Method as an Additional Security Control.
Make Single Sign-On Work Before Deploying Multi factor Authentication.
Don't Forget Mobile Users.
What is the most common form of identification and authentication?
Let's look into most common Identification and Authentication Methods: User I'd: It is the most standard form of identification and is used most often by organizations as a mode of identification to distinguish a user amongst others.
How do I authenticate a session?
Session based authentication is one in which the user state is stored on the server's memory. When using a session based auth system, the server creates and stores the session data in the server memory when the user logs in and then stores the session I'd in a cookie on the user browser.
What is the difference between session ID and session token?
HTTP is stateless, and in order to have an authenticated state, you need some kind of token used to reference information about the user. This session ID is usually in the form of a random token sent as a cookie value. An OAuth Access Token is used to identify a user, and the scope of resources that user has access to.
What is HTTP basic authentication and how it works?
HTTP basic authentication is a simple challenge and response mechanism with which a server can request authentication information (a user ID and password) from a client. The client passes the authentication information to the server in an Authorization header. The authentication information is in base-64 encoding.
