Kerberos is a security authentication protocol intended to provide More secure authentication Simplified management of password Convenience of single The basic structure of Kerberos Kerberos Client: The party requesting the service Kerberized Service: The party providing the services Kerberos KDC: A party that provides authentication for password management. Both client and service provider keep their privacy in the KDC. Kerberos Authentication Process

actually a type of dynamic cipher. Dynamic Password is also called a one-time password, which means that the user's password is constantly changing according to time or usage, and each password is used only once. Because each password used must be generated by a dynamic token and the user's password is different each time, it is difficult for a hacker to calculate the next dynamic password that appears. But dynamic passwords require a high demand for mobile phones, and smartphones like the ipho

Okhttp provides support for user authentication. When the status code for the HTTP response is 401, okhttp gets the new request object from the Set authenticator object and attempts to make the request again. The Authenticate method in the authenticator interface is used to provide a request object for authentication, and the Authenticateproxy method is used to provide a request object that authenticates th

difficult for a hacker to calculate the next dynamic password that appears. But dynamic passwords require a high demand for mobile phones, and smartphones like the iphone or Android are needed. Install two-step verification For Gmail users who are often attacked, it is highly recommended that Gmail's "Two-Step Authentication" feature be set up by logging into Google's account and then accessing the address, which allows the user to choose how to obtain the Authentication code: SMS, voice phon

you manually set up an additional token, then you do not need to attach this token. (2) header key is usually Authorization, if you are not this, you can modify. (3) If you need to refresh token when encountering such as 401 not authorised, you can use authenticator, which is a specially designed interceptor that asks for access to processing when the validation error occurs: Authenticator m

Here is the code I encapsulate, and the comments are more detailed. 1, the first is to inherit from the javax.mail.Authenticator of a specific class. the Getpasswordauthentication () method is to build a Passwordauthentication object and return, a little convoluted design intent such as Java Mail, It may be that Javax.mail.Authenticator has provided us with additional security verificat

First, the Mailauthenticator class is established and inherits from the Javax.

A fully modified desktop machine or a vigilant "sp" can log on to the SSL database before hitting the key information. In this case, the solution is to use the one-time password OTP) system. So far, in my opinion, OTP has brought more trouble than security. The cost and benefits OTP
