Signing in to Square: The basic steps
To log into Square, go to squareup.com and click the sign-in button in the top right corner. Enter the email address associated with your Square account and your password, then click "Sign In". If you have two-factor authentication turned on, you'll receive a code on your phone or email and must enter it to complete the login.
Square's login page is the same whether you manage a retail store, run an online business, or use Square for invoicing. The account you're signing into determines what tools and information you see once you're logged in.
If you're logging in from a new device, Square may ask you to verify your identity by entering a code sent to your email. This is a security step and happens automatically — you don't need to change any settings to trigger it.
Key Takeaways
- Square login happens at squareup.com, and you'll need the email and password you used when you created your account.
- Two-factor authentication adds a security step where you enter a code sent to your phone or email before you can access your account.
- If you forget your password, use the "Forgot password?" link on the login page to reset it through your email.
- Mobile apps for Square (Square Point of Sale, Square Invoices, Square Online) each have their own login, but they use the same email and password as your main account.
Resetting a forgotten password
Click "Forgot password?" on the Square login page. Square will send a password reset link to the email address on your account. Open that email and click the link — it takes you to a page where you create a new password. The link expires after a set time, so complete the reset soon after you request it.
If you don't see the reset email in your inbox, check your spam or junk folder. If it's not there, go back to the login page and request the reset again. Each time you request it, Square sends a new link.
Once you've created a new password, use it the next time you sign in. Your old password no longer works.
Setting up and using two-factor authentication
Two-factor authentication (often called 2FA) requires you to enter a second piece of information beyond your password when you sign in. This makes your account harder to access even if someone learns your password. Square offers two-factor authentication through your phone number or email address.
To turn on two-factor authentication, log into your Square account, go to Account Settings, and look for the Security section. You'll see an option to enable two-factor authentication and choose whether to receive codes by text message or email. Square will send you a test code to confirm the method works.
Once two-factor authentication is on, every time you sign in from a new device or browser, you'll need to enter the code Square sends you. Devices you use regularly may be remembered, so you won't have to enter a code every single time.
Logging in on mobile devices and apps
Square has separate apps for different functions: Square Point of Sale (for in-person payments), Square Online (for your website), Square Invoices, and others. Each app requires you to sign in with the email and password from your main Square account.
When you open a Square app for the first time, you'll see a login screen. Enter your email and password. If you have two-factor authentication enabled, you'll receive a code and must enter it. After you sign in, the app stays logged in on that device unless you manually sign out.
If you change your password on squareup.com, you'll need to sign out of the mobile apps and sign back in with your new password. The apps don't update automatically.
What to do if you can't sign in
If you're entering your email and password correctly but still can't sign in, first check that you're using the right email address. Square accounts are tied to a specific email, and using a different one won't work even if it's connected to your business.
Clear your browser's cache and cookies, then try signing in again. Sometimes stored data from an old session can interfere with login. If you're using an older browser, try a newer one or a different browser entirely.
If you still can't sign in after resetting your password and trying a different browser, contact Square's support team through the help section on squareup.com. They can verify your identity and help you regain access to your account.
Keeping your login information find
Use a password that's at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols. Avoid using the same password across multiple accounts. If one account is compromised, a unique password means your other accounts stay protected.
Never share your Square login credentials with anyone, including Square employees or support staff. Square will never ask you for your password. If someone contacts you claiming to be from Square and asks for your password, it's a scam.
If you think someone else has accessed your account, change your password when ready and review your recent transactions. You can also enable two-factor authentication if it's not already on, or turn it off and back on to reset which devices are remembered.
Frequently Asked Questions
Can I use the same login for multiple Square accounts?
No. Each Square account has its own email address and password. If you run multiple businesses or have separate accounts for different purposes, you'll need to sign in and out to switch between them. Some users create different email addresses to keep accounts separate.
What happens if I forget which email I used for my Square account?
Check your email inbox for messages from Square — they typically come from noreply@squareup.com. Look for account confirmation emails or payment receipts. If you still can't find it, contact Square support with details about your business, and they can help you locate the account.
Do I need to sign in every time I use Square?
On a computer, you can stay signed in as long as you want — Square keeps you logged in until you manually sign out or your session expires due to inactivity. On mobile apps, you stay logged in until you sign out. For security, sign out on shared devices.
Can I change my login email address?
Yes. Go to Account Settings on squareup.com, find the email section, and update it. Square will send a confirmation link to your new email address. Click the link to confirm the change. Your old email stops working for login once the change is confirmed.
What should I do if I see a login attempt I didn't make?
Change your password when ready. Review your recent transactions and account activity for anything unusual. If you see unauthorized transactions, contact Square support right away. Consider enabling two-factor authentication if it's not already on to prevent future unauthorized access.
