What is algorithm PPT?

An algorithm is a precise step-by- step plan for a computational procedure that possibly begins with an input value and yields an output value in a finite number of steps in order to solve a particular problem.

How secure is OTP?

An OTP is a password that is only valid for one login session, which means it is less vulnerable to replay attacks than a traditional password. OTPs are created within an app running on a user’s device—rather than sent via SMS message—so they are inherently more secure.

Now a days OTP’s are used in almost every service like Internet Banking, online transactions, etc. They are generally combination of 4 or 6 numeric digits or a 6-digit alphanumeric.

What is an algorithm in everyday life?

Algorithms can be used to sort a large set of information based on a set of structural rules, such as step by step instructions. For example, usually when you search for something on Google, there are many results, even pages and pages of results.

What is login authentication and how does it work?

The login authentication system is very common for any web application. It allows registered users to access the website and members-only features.

You can make it simpler using http basic authentication, but it looks clunky to the user. In rails, the most basic approach is to add the following to a controller A simple user login system should be based on one way hashing algorithm such as MD5 and SHA1.

How to create a signup system for your website?
