In a word, No...
Unfortunately, we do not have, and will never have, access to your password. All is not lost though because it's quite easy to set a new password.
simply click the "Login" text on the top menu, and then click "Request new password". On the next screen enter either your login name or the email address you registered with. The system will then email you a "one shot" password. (check your inbox and junk folder)
You can then use this temporary password to login to St Johns Online and change your password to something more memorable.
If you are still having trouble after trying this, please email jane@stjohnshillingdon.org.uk
