hello Mohini,
Before saving in the database you can use salted MD5 hash encryption. Outsystems use the same encryption technique.
I have also come across such a requirement where I was creating users from the screen, there we have used this.

And For user login use can use Validate Password. Where you will pass
Password user has entered in input parameter plain text password
The encrypted password you have stored in a database for a particular user
The output will be a boolean value as per the validation
