If you want to restrict access to your entire SmugMug site, you're in the right place.
If just certain galleries concern you, you'll prefer this help section.
What it does
When a password is set:
A lock icon appears next to your name on your homepage.
Your name, galleries, photos and keywords are removed from SmugMug's site-wide search. This can take a few minutes.
Your admirers will be asked for the site password on your homepage, category & subcategory pages, and gallery pages without passwords. If your admirers follow a link directly to a password-protected gallery, they will be asked only for that gallery's password.
Setting a site-wide password
You can set a site-wide password in the Privacy tab of your Account Settings. Enter a password in the field next to "Set site viewing password."
Want to give a password hint? It's an option. Your admirers will see it when they're asked for the password.
You can also allow friends and family to skip the password. Note: They will have to be logged into SmugMug for us to recognize them as your friend or family.
Q: Hold on. I wasn't asked for a password.
A: You won't be if (a) you're logged in or (b) you entered it in the last week on that computer. It's to keep us from making sane people crazy by prompting for the password too often.
Q: How do I clear the password?
A: Just empty the password field.
Q: Does this foil Google?
A: Yes. Your name, bio, gallery names, etc., should not appear in Google's search unless you place them on non-SmugMug pages.
