| <P> |
| <code>AuthenticationInfo</code> represents a Subject's (aka user's) stored account information relevant to the |
| authentication/log-in process only. |
| <p/> |
| It is important to understand the difference between this interface and the |
| <A HREF="../../../../org/apache/shiro/authc/AuthenticationToken.html" title="interface in org.apache.shiro.authc"><CODE>AuthenticationToken</CODE></A> interface. <code>AuthenticationInfo</code> implementations |
| represent already-verified and stored account data, whereas an <code>AuthenticationToken</code> represents data |
| submitted for any given login attempt (which may or may not successfully match the verified and stored account |
| <code>AuthenticationInfo</code>). |
| <p/> |
| Because the act of authentication (log-in) is orthogonal to authorization (access control), this interface is |
| intended to represent only the account data needed by Shiro during an authentication attempt. Shiro also |
| has a parallel <A HREF="../../../../org/apache/shiro/authz/AuthorizationInfo.html" title="interface in org.apache.shiro.authz"><CODE>AuthorizationInfo</CODE></A> interface for use during the |
| authorization process that references access control data such as roles and permissions. |
| <p/> |
| But because many if not most <A HREF="../../../../org/apache/shiro/realm/Realm.html" title="interface in org.apache.shiro.realm"><CODE>Realm</CODE></A>s store both sets of data for a Subject, it might be |
| convenient for a <code>Realm</code> implementation to utilize an implementation of the <A HREF="../../../../org/apache/shiro/authc/Account.html" title="interface in org.apache.shiro.authc"><CODE>Account</CODE></A> |
| interface instead, which is a convenience interface that combines both <code>AuthenticationInfo</code> and |
| <code>AuthorizationInfo</code>. Whether you choose to implement these two interfaces separately or implement the one |
| <code>Account</code> interface for a given <code>Realm</code> is entirely based on your application's needs or your |
| preferences. |
| <p/> |
| <p><b>Pleae note:</b> Since Shiro sometimes logs authentication operations, please ensure your AuthenticationInfo's |
| <code>toString()</code> implementation does <em>not</em> print out account credentials (password, etc), as these might be viewable to |
| someone reading your logs. This is good practice anyway, and account credentials should rarely (if ever) be printed |
| out for any reason. If you're using Shiro's default implementations of this interface, they only ever print the |
| account <A HREF="../../../../org/apache/shiro/authc/AuthenticationInfo.html#getPrincipals()"><CODE>principals</CODE></A>, so you do not need to do anything additional.</p> |
