I have no idea why do you see any tampering at all. To avoid a problem, one needs to have a problem.

Hi Developer,

Just do some more security levels in your application. Like

1. encrypting your username and password.
2. Enabling https.

I agree your solutions, and i did username and password encryption. but i need dynamic password encryption.

example:

1st time login:
password: abcd ---> zxcvbn12zx(encrypted password)

2st time login:
password: abcd ---> 45weqeeqeqe(encrypted password)

where login password is same but encrypted value is differ , i need like this.,

kindly give me any solution.
