It’s common practice for software developers to put options in their programs to save password. Web browsers allow one to save passwords. This is terrible functionality to have built into any program. Passwords are there for a reason. They are there to keep others out and let you in. Saving passwords in your browser is a terrible habit to start. This is especially true with a laptop.
If your computer is stolen, the thief not only has a nice new toy, they also have access to anything you have saved on the laptop. All one has to do to access passwords on your browser is open up the browser options and manage stored passwords.
There’s also the factor of forgetting your own passwords. Saving your password makes in much more likely that you’ll forget the password.
There’s no real good reason to store your password. Storing passwords is not only a lazy practice, it is also a terrible “feature” of any software.
