When you perform a Subversion operation that requires you to authenticate, by default Subversion caches your authentication credentials on disk. This is done for convenience so that you don’t have to continually reenter your password for future operations. If you’re concerned about caching your Subversion passwords,^[3] you can disable caching either permanently or on a case-by-case basis.

To disable password caching for a particular one-time command, pass the --no-auth-cache option on the command line. To permanently disable caching, you can add the line store-passwords = no to your local machine’s Subversion configuration file. See Client Credentials Caching for details.
