BSS B2B Lock: age verification
Age Verification Popup in BSS B2B Lock: Setup and Limits
The age verification popup in BSS B2B Lock asks each visitor to confirm a minimum age you set, such as 18 or 21, before they see the store, a product or a collection. Enter Site lets them in. Exit sends them to a URL you choose. It is a self-declaration: the app checks no birth date or ID.

What the age verification popup does
BSS B2B Lock puts a popup over the page with two buttons, Enter Site and Exit. The page behind it is blurred. A visitor who clicks Enter Site gets in. A visitor who clicks Exit goes to the URL you set, which defaults to /index.
You choose the minimum age. Eighteen and twenty-one are common, and any number works. The popup is one condition inside a lock rule, called Age verified: Must confirm age, so it sits next to the other Lock conditions. When a rule holds several conditions, a secret link and a passcode run first, then age verification, then date and time and customer tag rules.
The popup is a self-declaration. The visitor says they are old enough and the app takes their word for it.
What you can set in the popup
Everything below is edited in the Customize message window of the lock, and the preview updates as you type.
| Setting | What it controls | Note |
|---|---|---|
| Lock target | Where the popup appears: the entire store, selected products or selected collections | The Variants and Price and add to cart targets do not offer age verification |
| Minimum Required Age | The age shown in the popup | Any number. Use 18, 21 or your own |
| Heading and description text | The title and the message | A placeholder in the description is replaced by the minimum age, so you edit the age in one place |
| Button labels | The text on the confirm button and the exit button | For example Enter Site, I am 18 or older, Exit |
| Colors | Popup background, title, both buttons and both button texts | Defaults are a white background, a black title and white button text |
| Redirect URL (On Exit) | Where the Exit button sends a visitor | Default is /index. The user guide suggests a page that explains the age rule |
| Custom CSS | Overrides the default popup styles | For advanced users |
| Require Date of Birth, background image | A date of birth field and a popup background | Shown in the app as Coming Soon. They cannot be turned on yet |
How do I set up the age verification popup in the admin?
These steps follow the BSS B2B Lock user guide and the app code as reviewed in October 2026.
-
Create a lock and choose the target
In Shopify admin open Apps, then BSS B2B Lock, then Locks, and click Add lock rule. Choose Create my own lock, name it, then open What do you want to lock? and pick Entire store, Products or Collections.
-
Add the Age verified condition
In Step 2, Access and Message, open More and choose Other condition. In Select access rule pick Age verified: Must confirm age, then click Done.
-
Set the minimum age
On the Preview card click Customize message. Under General Configuration enter the Minimum Required Age and check the preview.
-
Style the popup and choose the exit page
Set the colors under Appearance and the Redirect URL (On Exit) under Behavior. In the content section edit the heading, the description and both button labels.
-
Save and test in a private window
Save the lock and open the storefront in a private browser window. Check that the popup shows on a covered page, that Enter Site lets you in and that Exit lands on your redirect page. Test again in a new private window, because a confirmed visitor does not see the popup again while the same cart exists.
Start with the entire-store popup on the Free plan. Targeting products or collections needs a paid plan. The listing shows a 7-day free trial on paid plans.
How the app remembers a visitor
When a visitor clicks Enter Site, the app writes a cart attribute named age-verified plus the ID of the age condition on the Shopify cart, then reloads the page. The lock passes while that attribute is on the cart. Nothing is stored in a cookie.
So the popup comes back when the cart is cleared, or when the visitor switches browser or device. How long a cart lasts depends on Shopify, so we do not promise a number of days. The user guide lists the returning popup as expected behavior.
What are the limits of the age verification popup?
Read these before you decide whether the popup is enough for your products.
A determined visitor can get past it
The popup blurs the page and blocks clicks with CSS. On an age lock the page content stays in the HTML, and the confirmation is a cart attribute that a technical visitor can set. Treat it as a notice for ordinary visitors, not as a barrier.
It does not make a store compliant
The popup does not satisfy any law or rule on its own. If you sell age-restricted goods, check the requirements for your products and market and use a method that fits them.
Three targets only
Age verification works on the entire store, products and collections. The Variants target shows a warning in the app that locking variants does not support age verification.
Standard storefront only
The user guide lists a standard Shopify online store as a requirement. Headless and custom frontends are not supported.
The popup is tied to the cart
A cleared cart, a new browser or a new device shows the popup again. Test in a new private window each time you change the lock.
Works with other Lock rules
Age verification is one condition in a lock rule. In the lock editor, a visitor must meet every condition in a rule to get in, and you can add more rules to let other groups in. A rule can therefore ask for an age confirmation and, for example, a passcode together.
If your catalog is for trade buyers only, a login or customer tag lock on a page, product or collection is the stronger tool, because it removes the real content from the HTML for visitors who do not qualify. The age popup suits an open store that needs a notice before browsing.
Which BSS B2B Lock plan do I need for age verification?
BSS B2B Lock has a Free plan that locks the entire store by condition. Paid plans add hiding products, collections and pages, locks by URL or customer tag, passcodes and checkout locks. Paid plans start at $9.99 per month with a 7-day free trial on paid plans, and the tier follows your Shopify plan. Prices are from the App Store listing on October 10, 2026.
On the Free plan only the entire store target works. Products and collections need a paid plan or the trial. Questions about your plan go to [email protected].

Frequently asked questions
Is the age verification popup a legal age check?
No. It is a self-declaration: the visitor clicks Enter Site to say they meet the minimum age. The app does not check a birth date or an ID, and the Date of Birth option is still marked Coming Soon. Check the rules for your products and market before you rely on it.
Can I set the minimum age to 21 instead of 18?
Yes. Enter any number as the Minimum Required Age, such as 18 or 21. If your description text uses the age placeholder, the popup shows the number you set, so you only change the age in one place.
Can I show it only on some products or collections?
Yes. The lock target can be the entire store, selected products or selected collections. Prices, Add to cart and variants do not offer age verification. On the Free plan only the entire store target works. Products and collections need a paid plan or the trial.
How long does a visitor stay verified?
The confirmation is saved as a cart attribute on the visitor's Shopify cart. The popup stays away while that cart exists and returns after a cleared cart or on a new browser or device. We do not publish a fixed duration because it depends on the cart.
What happens when someone clicks Exit?
The visitor goes to the Redirect URL (On Exit) that you set. The default is /index. The user guide suggests a dedicated page that explains the age restriction. You can also change the Exit button text in the same window.
