bitLogin

One tap to sign in — and a customer you can reach again.

bitLogin lets shoppers sign in to your Shopify store with Google, WhatsApp OTP, Apple, and more — no password, no new account. Smart forms and pop-ups capture first-party data, and every sign-in writes a real, recognized customer to the same bitCRM record your agent uses — so a checkout becomes a relationship, not an anonymous order.

What you get

More logins. More data. More sales.

bitLogin does three jobs at one tap: it clears the account-creation wall in front of checkout, captures the shopper behind it as first-party data, and turns that data into a customer you can recognize and re-reach.

More logins

One tap with the accounts shoppers already use — Google One Tap, WhatsApp OTP, Apple, and 10+ more. No password to create means fewer abandoned sign-ups at the worst possible moment.

More data

Smart sign-up forms and voucher pop-ups capture the fields you choose — phone, preferences, and more — as first-party data, written straight to your bitCRM record.

More sales

Each sign-in becomes a named customer the agent can greet and re-reach — and a list you own, segment, and export. Not an anonymous order you have to win back from scratch.

Sign-in

Sign in with the accounts they already have.

Offer the logins your shoppers already trust, in the order that converts best for your store — then style the whole thing to your brand so it never looks bolted on.

  • 10+ ways in — Google, Apple, Facebook, Instagram, Microsoft, Twitter/X, and Amazon, plus Magic Link; pick which to show and in what order
  • WhatsApp OTP — a one-time code over encrypted WhatsApp verifies the shopper in seconds: faster and safer than SMS, and it cuts fake accounts
  • Google One Tap — returning Google users sign in without even opening the form
  • Themed, not generic — adjust placement, size, and color, and put the buttons above or below your regular login

Forms & pop-ups

Forms that capture data, pop-ups that capture sales.

A login gets you the customer; a form gets you everything else. Add a smart sign-up form to collect the fields that matter, and a one-tap voucher pop-up to convert a browser before they leave — all writing to the same record.

  • Smart fields — collect phone, birthday, sizes, and preferences; mark any field required and show fields only when they’re relevant
  • Voucher pop-ups — a one-tap “15% off” offer turns a sign-up into a first order, captured the moment they opt in
  • Straight to the record — every form and pop-up lands on the same bitCRM profile, segment-ready — no export, no copy-paste
Login → record

One login writes one record.

bitLogin doesn’t leave the sign-in stranded on Shopify. Every login lands on the same bitCRM customer record your WhatsApp agent reads from — so the customer is known across every surface, not re-created on each one.

  • Identity, captured — name, email, and the channel they used flow straight onto the profile
  • One record, every surface — a sign-in, a WhatsApp question, and a past order all sit on one customer, not three
  • WhatsApp sign-in adds the phone — when they choose WhatsApp, the record gets a phone number: the agent’s primary key for re-reaching them

A sign-in and a chat — one customer, one record.

The agent that recognizes them is built in AI Studio; everything a login captures lives in bitCRM. Turning those customers into reach is WhatsApp Marketing, and into repeat is loyalty & retention — points, tiers, and vouchers ship in bitLoyalty (Beta · requires Shopify) on the same record.

Recognition

Recognized the moment they come back.

Because a login ties a real identity to the record, the agent isn’t starting cold the next time that customer messages. It already knows who they are, what they bought, and what they were looking at — so it greets, not interrogates.

  • No “who am I talking to?” — the agent opens knowing the customer behind the message
  • Context before hello — past orders and saved items are on the record, not lost between sessions
  • Recognition, not tracking — the data exists to serve the customer better, and it’s yours to control

Welcome back, Dewi! The Sand Linen Shirt you saved is back in your size — want me to set one aside?

The agent greets a returning customer it already knows.

Owned customer data

The customer list you build is yours.

Most stores collect an anonymous order and an email they can barely reach. bitLogin turns each sign-in into a named, recognized customer on a record you own and can export — someone you can re-reach on WhatsApp or push, instead of renting access to them again every time.

Free to install — a customer list you keep, not one you have to win back from scratch.

Built on

Sign-in runs on each provider’s official OAuth, and WhatsApp login connects on Meta Cloud API as an Official Meta Tech Partner. Your customer data stays in your bitbybit workspace with full export — never sold, never locked away from you.

The short version

bitLogin adds 10+ one-tap, passwordless social logins to your Shopify store — Google (with Google One Tap), WhatsApp OTP, Apple, Facebook, and more — plus smart data-capture forms and voucher pop-ups, and writes every sign-in to the same bitCRM customer record your AI agent uses. Shoppers skip creating a password, so fewer sign-ups stall at checkout; and each login, form, or pop-up becomes a named, recognized customer — name, email, phone, and preferences captured onto a record you own and can export, not an anonymous session. The buttons match your theme with no code, and the customer you capture is the same one the agent recognizes on WhatsApp and that bitCRM can re-reach. Login is free to install on Shopify with unlimited logins and users, and the customers you capture are the on-ramp to repeat purchase in bitLoyalty (Beta · requires Shopify).

FAQ

Questions about bitLogin.

Do shoppers have to create a password? +

No. They sign in with an account they already have — Google, WhatsApp, Apple, Facebook, and more — in one tap. Nothing new to create or remember, which means fewer half-finished sign-ups at checkout.

Which sign-in methods does bitLogin support? +

More than ten one-tap methods — Google and Google One Tap, WhatsApp OTP, Apple, Facebook, Instagram, Microsoft, Twitter/X, Amazon, and Magic Link. You choose which to show and in what order.

Does bitLogin do more than login? +

Yes — it’s social login and forms. Smart sign-up forms capture first-party data — phone, preferences, and any field you add — and sign-up or voucher pop-ups turn a visitor into a subscriber. Everything lands on the same bitCRM record, so your marketing can act on it right away.

Do I need to be on Shopify? +

Yes — bitLogin adds social login to your Shopify storefront. You enable it on your theme with no code. If you’re not on Shopify, the agent still captures customers in conversation and writes them to the same bitCRM record.

Does it match my store’s design? +

Yes. Style the buttons to your theme — placement, size, and color — and put them above or below your regular login. The branded sign-in popup is yours, not a generic widget.

Where does the customer data go? +

Every sign-in writes the customer’s name, email, and the channel they used to your bitCRM customer record — yours to segment, message, and export. It exists so the agent can recognize and serve the customer, not to profile them, and your list is never locked in.

Can I turn new sign-ins into repeat buyers? +

That’s bitLoyalty (Beta · requires Shopify) — points, tiers, and vouchers built on the same record. Until then, bitCRM and WhatsApp Marketing re-reach every customer bitLogin captures.

Is it really free? +

Login is free — unlimited logins and unlimited users on the free plan, no credit card to install. Google One Tap, analytics, and smart data-capture forms unlock on paid plans. See /pricing for the full bitbybit suite.

Turn every sign-in into a customer you keep.
