Sign in
Sign in to SmileLine with your email and password or with Google or Apple, and reset your password when you forget it.
By the end of this page you'll be signed in and looking at your Today queue — the page SmileLine always opens first.
Sign in
Go to the SmileLine sign-in page, enter your Email, and click Continue.
On the regional login card, enter your Password and click Login. If your email has accounts in both service regions, choose the account you want first.
You land on Today, your daily work queue.
Don't have an account yet? Click Sign up on the login card and enter your Full name, Email and a Password (at least 8 characters). Tick I agree to Smileline's Terms of Service and Privacy Policy — the links open both documents, and your acceptance (version, time) is recorded to your account — then click Create account. After you choose your practice country you can also sign up with Continue with Google or Continue with Apple instead. If a colleague invited you, use the link in the invitation email instead — it takes you straight into their practice.
Sign in with Google or Apple
On the login card, click Continue with Google or Continue with Apple and approve the request with that provider. If you already have a SmileLine account under the same verified email address you're signed straight into it; if you're new, an account is created and you continue into practice setup.
If your account lives in the other service region, SmileLine retries there automatically — you may briefly see the provider screen a second time. When the region genuinely can't be determined, sign in with your email and password instead.
Signing in with Google or Apple skips SmileLine's two-factor verification: the provider's own protections — password, passkey, and device checks — stand in for it.
Apple can hide your real email address behind a private relay address. If your SmileLine account uses your real address, a first Apple sign-in with Hide My Email creates a separate, empty account instead of opening yours. To use Apple with an existing account, sign in with your password first and connect Apple under Settings → Account → Sign-in methods.
If SmileLine cannot reach the sign-in service, the login card shows an error and lets you try again. Check your connection before resubmitting your password.
If you reach the wrong service region, click Try EU account region or Try US account region after the failed login. You can also pin the region before you sign in: the selector in the top-right corner of the login card offers Auto, EU and US. Auto locates your account from the email address you enter; EU or US sends you straight to that region and is remembered on this browser. These choices are always available and do not confirm whether an account exists in a region.
Complete two-factor verification
If two-factor authentication is enabled on your account, Login opens a second verification page instead of signing you in immediately.
Open your authenticator app and enter the current six-digit code.
Click Verify and continue. SmileLine creates your signed-in session only after the code succeeds.
If you cannot use the authenticator, click Use a backup code instead and enter one unused backup code. Each backup code works once. Store the remaining codes somewhere private; they are not shown again after setup.
Five failed checks exhaust the current verification request. Return to Sign in and start again. Repeated failed requests can lock second-factor checks for 15 minutes; wait for the lock to end before trying again.
Reset a forgotten password
On the login card, click Forgot password?.
Enter your Email and click Send reset link. If an account exists for that address, a reset link is on its way.
Open the email and follow the link. Choose a New password (at least 8 characters) and click Reset password.
You're taken back to the login card — sign in with the new password.
Reset links expire. If the page says the link is invalid or has expired, click Request a new one and start again from your inbox.
Manage your sign-in methods
Open Settings → Account and find Sign-in methods to see what's connected to your account: Email & password, Google, and Apple.
- Connect sends you to the provider to approve the link, then returns you to Settings with the method attached. This is the safe way to add Apple to an existing account, whatever email Apple shows.
- Disconnect removes a method. Your last remaining sign-in method can never be removed.
- Changing sign-in methods requires a recent sign-in. If SmileLine asks you to sign in again first, do so and retry.
Staying signed in
Once you sign in, SmileLine keeps your session on that browser — you won't be asked for your password on every visit. On a shared front-desk computer, sign out when you finish: click your name at the bottom of the sidebar, then Sign out.
