Log in to Sintra

Learn how to log in to the Sintra App - with email, Google, or Apple - how to create a password for faster logins, and how to troubleshoot the most common login issues

Written by Emily

In this article, we’ll cover how to log in to Sintra for the first time, the different sign-in options, how to create a password if you’d rather not wait for a one-time code, how to log in later on, and how to fix the login issues you might run into.

Before you start: to log in, you need an active Sintra subscription.

If you enter an email that doesn’t have one, you’ll be sent to our pricing page automatically.

New here? Head to pricing to pick the plan that fits — then come back and log in.

Log in to Sintra for the first time

If it’s your first time trying to log in to Sintra.ai, make sure you have Sintra’s products purchased. If that’s done, follow the steps below.

You’ll see three ways to sign in. Pick whichever you prefer.

Option 1: Continue with Email (one-time code)

This is the default login flow - you can later on manually set up a password instead of a one-time passcode.

  1. Go to Sintra’s login page:
    ​

  2. Enter the email associated with your Sintra account — the same one you used at.
    ​

  3. Click “Continue with email”:
    ​

  4. In a new window, go to your email inbox, as a 6-digit One-Time Login Code will be sent to your email. Copy the code:
    ​


    ​Can’t find the code? Check your spam/junk folder first. If it’s still missing, see the troubleshooting section below.
    ​

  5. Go back to the login page and input the code to access your account:
    ​

Sintra uses one-time passwords by default, so each time you log in this way, you’ll get a fresh code.

Prefer a password? You can set one up yourself in a minute - see Create a password for easier logins in this article below.

Option 2: Continue with Google

Prefer a one-click sign-in? Click Continue with Google and choose the Google account tied to your Sintra subscription.

Option 3: Continue with Apple

You may also see Continue with Apple - sign in with the Apple ID linked to your subscription.

(This option is rolling out and may not appear on every account yet.)

Create a password for easier login (optional)

Don’t want to wait for a code every time? You can set up your own password in Settings - it takes about a minute.

Set up a password for Sintra AI by following the steps below:

  1. Log in to the Sintra app using any of the options above.
    ​

  2. Go to the Sintra App Settings page by clicking on the cog-wheel icon in the bottom-left corner.
    ​

3. Click Account.

4. Scroll down until you find the “Set up password” button:
​

5. Follow the prompts to create and confirm your new password.

That’s it. From now on, you’ll log in with your email and password.

Quick heads-up: once you have a password, Sintra asks for that instead of sending a code. If you ever want a one-time code again, just click Forgot password on the login screen, and we’ll email you one.

Login to Sintra continuously

To log in to Sintra App after you have set up a permanent password, you need to:

  1. Go to Sintra’s login page and enter your email address, which is associated with your Sintra account:
    ​

  2. Click “Continue with email”:
    ​

  3. Enter your password and click “Log in”:
    ​

Now you can access Sintra’s homepage!

Troubleshooting login issues

Didn’t get your one-time code?

  • Check spam/junk folder in your email - it’s the most common culprit.

  • Wait out the cooldown - there’s a ~60-second wait before you can resend a new code. Give the first one a moment to arrive before requesting another.

  • Slow down on retries - too many attempts in a row can temporarily rate-limit you. Wait a minute, then try again.

  • Confirm the email - make sure you’re using the exact address tied to your subscription (the one from checkout).

If you are experiencing issues with the Sintra app, such as login problems or repeated onboarding prompts, use the following troubleshooting steps to resolve it.

General Troubleshooting Steps

  1. Verify Account Status and Payment Processed

    • Ensure your Sintra account is active and fully recognized.

    • Confirm that your payment has been successfully processed. An inactive account due to an unsuccessful payment may prevent access to features.

  2. Check for Error Messages and Credentials

    • Verify your login credentials are correct.

    • Take note of any error messages, as these details can assist in further troubleshooting.

  3. Disable any VPN temporarily, as it can interfere with the login process.

  4. Try a different browser or an incognito/private window to rule out cached data.

  5. Update the Sintra App (if you are using a mobile app)

    • Ensure that you are using the latest version of the Sintra app. App updates can often fix bugs and resolve issues such as repeated logouts or failure to generate files.

Repeated Onboarding Prompts

If the Sintra mobile app prompts you to go through onboarding again unexpectedly, follow these steps:

  • Uninstall the Sintra app from your device.

  • Reinstall the app from your device's app store.

  • Open the app and sign in again. Reinstalling the app refreshes its settings and clears corrupted data that may cause onboarding loops.

If the Sintra browser app prompts you to go through onboarding again unexpectedly, follow these steps:

  • Try logging in on an incognito browser.

  • Try logging in on a different browser.

  • Try logging in on another device.

Persistent issues

Still stuck? Message our support team with the email you’re using and a quick note on what you’re seeing, and we’ll get you sorted.
