Share Your Story...

This application has been around for many, many years and served my purposes for keeping track of not only passwords, but important and very private notes. I can even use it to log small bits of information, such as when a credit card is lost, or whom I talked to to resolve an issue, or how I may have more than one password for an account, etc. It's very customizable, which I love. I also like that it works on both my Mac and my iPhone, though syncing between the two is still not really automatic. But it still needs to support fingerprint logins on iPhone 6 and newer, and could improve the display of information on small computer screens. Overall, still my best go-to password application for Mac and iPhone.

Using it since 6 years ago. It's great.

Jesús Rodríguez

Always had post-it notes and loose scraps of papers with my logins and passwords scattered around my desk. Data Guardian helped eliminate the clutter and misplaced info and keeps everything in one place for me to access.

Steven Czarnecki

With so many unique passwords and other private information Data Guardian is the easiest way for me to have them available on my iPhone and iMac.

ed gunderson

I rely on this program every day. I store all my passwords and logins and use it daily to launch the URL's to access my accounts. There's no better program for this. I've tried others but none compare.

Richard Dion

good for storing myriad passwords.

Bill White

I have been using Data Guardian FOR YEARS! and I love it!

KathyAnne Whittemore

Once upon a time I bought software from a reputable company at a fair price and it actually worked (to my surprise) as advertised, yeah me! But I stared to be concerned the as has happened to me in the 30 years that I have been using software both personally and professionally that the above mentioned "reputable company" sold out leaving the customer with it's pants down. PLEASE! don't do that! THANKS IN ADVANCE.

Gerard C. Pilachowski

works like a charm.....

Hubert Reisenauer

I create and store all user name and password combos for everything I access on the internet through use of this software, even for smart phone apps. I was recently tempted to switch to "One Password", but didn't see much difference, and didn't want to spend the extra time trying to export all of my data. One of the early versions of Data Guardian had a "clickable" button to allow the activation of the chosen URL. That feature was discontinued along the way, and I still miss it. I'd like to have such a feature made available again. I'll give a "5" rating if that is reinstated.
