ChangeMyPasswords

Generally speaking, one of the recommendations you should take into account to keep your accounts safe is to change your passwords on a regular basis. While the cornerstone of account security, the task can be tedious and can sometimes take a lot of time to complete.
ChangeMyPasswords is a light piece of software that enables you to quick and efficiently modify your password to the dozens of websites, applications and services you have an account for in a matter of minutes.

Comes with a rugged, yet intuitive interface

Following a quick and forthright installation, you are welcomed by an unpolished, yet user-friendly and structured interface. While a vast percentage of the main window is dedicated to viewing the websites or the results of passwords changes you made from imported files, in the upper section of the UI, you can preview the available commands.
It is necessary to mention that the application works with numerous websites and that you can find a comprehensive list of the supported sites on the developer's site. In case you do not find a particular site in the list, then you can consider adding it via the Add Website Request function. You should bear in mind that the feature is available when launching the app and that it can take up to 4 days to add a new site.

Allows you to change all passwords in one go

The idea behind the application is to provide you with a quick way to change all your passwords all at once. Consequentially, it has been designed to work with the most popular password managers, including but not limited to Keepass, Mozilla Password Exporter, PW Agent, PW Safe, DashLane and Lastpass.
As you probably hinted, you need to have a password file in order to make the necessary modifications. If you do not use a password manager, you can create a file using any text editor you want and then use the app to process it. However, you need to make sure that the file respects a basic format, namely website name, userID and password on each line.

An effective app for modifying all your passwords simultaneously

In the eventuality that you have accounts for dozens of applications, websites and other online services and you would like to change the passwords to enhance security, then ChangeMyPasswords could lend you a hand.
