I was setting up another user to use our SVN repository. He didn't have a username/password, so I logged in with my credentials. We now have a username/password for him.
How do I get TortoiseSVN to logout and forget the old password so I can enter the new username/password?
- Open Windows Explorer.
- Right-click anywhere in the window.
- Click TortoiseSVN → Settings.
- Click Saved Data.
- Click Clear beside Authentication Data (see below).
- Check the authentication items to clear.
- Click OK.
All saved Authentication Data for all projects is deleted.
You will have to re-enter credentials to reconnect.

- Right click
- TortoiseSVN
- Settings
- Saved Data
- Authentication data - Clear
There are several ways to do it, through settings or by deleting the cache.
Deleting the cache is the most versatile method. First, locate it:
On XP, it was located here:
C:\Documents and Settings\%USER%\Application Data\Subversion\auth\svn.simple\
On Vista, it was located here:
C:\Users\%USER%\AppData\Roaming\Subversion\auth\svn.simple\
Then look in those files with Notepad, and delete the one with your credentials.
If you want to remove only one saved password, e.g. for "user1":
- Go to the saved password directory (
*c:\Users\USERNAME\AppData\Roaming\Subversion\auth\svn.simple\*
) - You will find several files in this folder (named with hash value)
- Find the file which contains the username "user1", which you want to change (open it with Notepad).
- Remove the file.
- Next time you will connect to your SVN server, Tortoise will prompt you for new username and password.
After struggling with this and trying all the answers on this page, I finally realized I had the incorrect credentials stored by windows for the server that hosts our subversion. I cleared this stored value from windows credentials and all is well.
Replace the line in htpasswd file:
Go to: http://www.htaccesstools.com/htpasswd-generator-windows/
(If the link is expired, search another generator from google.com.)
Enter your username and password. The site will generate an encrypted line. Copy that line and replace it with the previous line in the file "repo/htpasswd".
You might also need to Clear the 'Authentication data' from TortoiseSVN → Settings → Saved Data.
