When a user needs to enter some sensitive information such as passwords, credit card information, and bank accounts, the user prefers to manually press the data through the keyboard, instead of copying and pasting the data through the clipboard.
Let's take a look at the effect after implementation:
Enter New Password
Copy the new password. The following dialog box is displayed.
