Subversion server does not require user authentication on every request. When you use the Subversion integration from within PyCharm, you only need to answer the authentication challenge of the server, if it is required by the authentication and authorization policies. The successful authentication results in saving your credentials on disk, in ~/.subversion/auth/ on Unix systems or <USER HOME>/.subversion_IDEA on Windows and OS X.
When an authentication challenge comes from the server, the credentials are sought for in the disk cache; if the appropriate credentials are not found, or fail to authenticate, the users is prompted to specify the login name and password.
If necessary, you can opt to delete all credentials stored in cache, for http, svn and ssh+svn protocols.
