Request: The person asks for access to a server or protected resource.

In return, they'll get a token that allows access for a time period you define. Use a token-based authentication system, and visitors will verify credentials just once. But even when they complete those preliminary steps perfectly, they can't gain access without the help of an access token.

They may need to enter a password or answer a question. In all three of these scenarios, a user must do something to start the process. If you've ever used your phone for a two-factor authentication process, you've used this type of token.

Disconnected: A device can communicate with the server across long distances, even if it never touches another device at all.

Microsoft's so-called " magic ring" would be an example of this type of token.

Contactless: A device is close enough to a server to communicate with it, but it doesn't plug in.

If you've ever used a USB device or smartcard to log into a system, you've used a connected token.

Connected: Keys, discs, drives, and other physical items plug into the system for access.

These are three common types of authentication tokens: 3 Authentication Token TypesĪll authentication tokens allow access, but each type works a little differently. And the session's record takes up no space on the server. The user may still have one password to remember, but the token offers another form of access that's much harder to steal or overcome.

When verification is complete, the server issues a token and responds to the request. With token authentication, a secondary service verifies a server request. Each time the person logs on, the computer creates a record of the transaction. Passwords also require server authentication.

People change one letter or number when prompted to update a password. If one password is discovered, many accounts may be vulnerable. People tend to use the same password in multiple places. Loose pieces of paper filled with passwords are security nightmares. People can't remember all of their passwords, so they resort to tricks, such as: In fact, one of the first documented cases of password theft happened all the way back in 1962. Whenever the user needs to access something, the password has to be entered. The person must keep that unique combination in their mind. Someone comes up with a combination of letters, numbers, and symbols. It wasn't always effective.Ĭonsider passwords. We used traditional methods to ensure that the right people had access to the right things at the right time. Before we had authentication tokens, we had passwords and servers.

A History of Authentication TokensĪuthentication and authorization are different but related concepts. Let's dig in, so you can determine if tokens are right for you and your organization. Most developers pick up the techniques quickly, but there is a learning curve. Tokens offer a second layer of security, and administrators have detailed control over each action and transaction.īut using tokens requires a bit of coding know-how. Token-based authentication is different from traditional password-based or server-based authentication techniques. Once the user logs out or quits an app, the token is invalidated.

The user retains access as long as the token remains valid. During the life of the token, users then access the website or app that the token has been issued for, rather than having to re-enter credentials each time they go back to the same webpage, app, or any resource protected with that same token.Īuth tokens work like a stamped ticket. Token-based authentication is a protocol which allows users to verify their identity, and in return receive a unique access token.
