All your login/password remain in your computer. We can't access it.
When on IRCTC Bank selection page, it automatically selects SBI Netbanking option. When you select "Make Payment" then it automatically logs you in SBI account, and presses all the buttons. Except for SMS confirmation it does everything else.
Your payment should be over in 2-3 seconds instead of 1 minute.
If you've filled up login and password and have it saved using "Save" button, click this link and verify that you are indeed logging into your SBI account automatically. If the SBI page takes more time to load then this may not work, then try clicking this button at different times until it succeeds. Otherwise when booking IRCTC ticket, you will waste your time in entering the login/password.
Note: "One click login" works only from here and when paying through IRCTC. This login link expires in a few seconds.
The password will be kept in Browser's memory as long as it is open. Once you close all Google Chrome browsers or Shutdown(not Hibernate/Sleep) your computer, the password will be gone. It will never written on disk. So you're 100% safe if you don't forget to close Chrome Browser or Shutdown the computer.
The password will be saved on Hard disk for 1 day only. Upon next browser restart it will be deleted after 1 day. But if you start the browser say after 1 year, then it'll be deleted on Browser restart only. In short for 1 Day, 1 Week and 1 Month options to work and password be deleted, the browser must be opened on date past otherwise the password will remain on Chrome's disk storage.
Same applies for 1 Week and 1 Month options.
Until Browser Is Open is strongly RECOMMENDED
