A pass­word man­ager is a soft­ware appli­ca­tion that stores pass­words, passphrases, credit card num­bers, PINs, TANs, secu­rity ques­tions, PGP encryp­tion keys, and other valu­able infor­ma­tion securely and allows for easy and fast access by the user.

The infor­ma­tion stored within a pass­word man­ager usu­ally is encrypted using a sin­gle strong mas­ter pass­word. This pass­word has to be pro­vided to gain access to its infor­ma­tion. A pass­word man­ager allows you to use dif­fer­ent strong pass­words for every web­site you log in to, every sys­tem you use and every appli­ca­tion that requests pass­word authen­ti­ca­tion. All with­out hav­ing to worry about remem­ber­ing more than one mas­ter pass­word.

Most pass­word man­agers addi­tion­ally offer a pass­word gen­er­a­tor let­ting you gen­er­ate strong pass­words using alphanu­meric, spe­cial and punc­tu­a­tion char­ac­ters in ran­dom order.

Many pass­word man­agers even inte­grate seam­lessly into your device. They allow you to eas­ily fill­ing pass­word fields of web­sites, or let­ting you copy/paste pass­words into other appli­ca­tions.

Thus, pass­word man­agers sim­plify your entire user expe­ri­ence when deal­ing with secure pass­word authen­ti­ca­tion.
