I cannot login to Shutterfly from within Photos. The shutterfly extension pops up as a Share but when it asks for my login ID and password, it continues to tell me invalid login or ID. If I login to Shutterfly from my browser, the loginID and password work perfectly. This question has been asked before without a workable answer and many people indicate that they have the same problem. It is not a Shutterfly problem.

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.
NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following;
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts
• Deletes font caches, kernel cache, and other system cache files
NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.
