When we want to log in to some website, a user name and password are needed to log in.
After successfully "logging in" in the google chrome browser, the google chrome browser asks to save the password.
Then most of the time we save the password on our mobile phone or android phone for the ease of access to the website next time.
After a long time or a few days, we may forget the passwords. But no tension, the google chrome browser saved the passwords. To know the saved passwords just follow the steps.
