change tortoise svn password to connect with

Hello, somehow when I update the repository, another username/password is being use.  I think this happened because I recently configured another program to use svn.exe to use this username/password, but I don’t want all my regular work using this.  I didn’t see any obvious options to change this once I put this in, can someone help me change this?

Tortoise SVN | Settings | Saved Data | Authentication Data | Clear

That will clear the stored information, and you will be prompted for
it the next time it’s needed.
