Follow these steps
a) Right click on local code repo
b) Go to TortoiseSVN > Settings
c) Go to “Network”
d) Browse for SSH Client and use following
“C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe” – Can be found in TortoiseSVN installation folder in c:\Prgram Files
d) Append following replacing username and password with your user name and password
“-l username -pw password”
e) Click OK/Apply
That’s it. 
Does this allow you to have different login/passwords for different projects?
I never tried it. Now I work on Debian and not sure if it is possible or not.
That’s brilliant, going to save us loads of time with the number of commits we make!
