- Short answer
- Yes — Shopify's sign-in guide says it's on by default without Shop Pay and can be turned off; with Shop Pay, only deactivating Shop Pay removes it.
- With Shop Pay active
- Only deactivating Shop Pay removes Sign in with Shop storewide; no per-customer opt-out.
- Where to switch it
- Settings › Customer accounts › Authentication › Manage › Turn off, on stores without Shop Pay, per Shopify's guides.
- Account versions
- Works on new and legacy customer accounts; Shopify's help pages disagree on the default for each.
- Theme Shop buttons
- Adding Shop sign-in buttons in the theme editor needs the Shop channel and Shop Pay.
Does Sign in with Shop need Shop Pay?
No. Shopify's Sign in with Shop guide says that without Shop Pay activated, it's activated by default and you can turn it on or off in your customer accounts settings. With Shop Pay, it's turned on automatically and can only be removed if you deactivate Shop Pay.
Customers sign in with their Shop credentials and saved passkeys, and Shopify collects associated data directly from those who choose Sign in with Shop. On new customer accounts, you always get their Shop email on the customer record, per an April 2023 changelog.
How do you turn off Sign in with Shop?
Without Shop Pay, you can switch it off yourself.
- Settings
- Customer accounts
In the Authentication section, click Manage, then Turn off next to Sign in with Shop. Shopify's legacy accounts page gives the same steps.
Theme-editor Shop sign-in buttons are separate: they need the Shop channel and Shop Pay activated (Shop buttons guide, our Shop channel guide).
Does it work on legacy customer accounts?
Yes, on new and legacy customer accounts alike, but Shopify's pages, read October 18, 2026, disagree on the default for each account version.
The sign-in guide and the legacy accounts page say legacy has it on by default without Shop Pay. The feature comparison says legacy “can be turned on manually in your settings,” and new accounts get it “turned on automatically for stores using Shop Pay, or for stores on the Shopify, Advanced, or Retail plans.” (Shopify's developer changelog says the plan previously known as Shopify was renamed Grow.) The customer accounts overview mentions only stores with Shop Pay.
So don't infer the default from these pages: the Sign in with Shop item in Settings › Customer accounts shows your store's actual state.
