- Sign up in the official Sezzle app with your phone number and identity details that exactly match your bank records.
- Log in with your phone and a one-time code; most login problems come from code delays, number changes or outdated apps.
- Protect your account with biometrics, current contact details and a healthy suspicion of texts or links asking for codes.
A clean setup in the Sezzle App does more than get you shopping — it affects your spending power and whether you will later qualify for Sezzle Cash. Here is how to sign up, log in and keep your account safe.
How to sign up for the app
- 1Install the official app
“Sezzle – Shop, Save, Earn” by Sezzle Inc. on the App Store or Google Play.

- 6Review your spending power
, which appears after a soft credit check that does not affect your score.
Your first week in the app
Getting approved is step one. What you do in the first few days shapes how useful the account becomes.
- 1Turn on notifications
Payment reminders are the simplest way to avoid a missed installment.
- 2Check your linked bank account
Make sure the default payment method is the account your paycheck lands in.
- 3Start small
Make one modest purchase you were going to buy anyway and pay every installment on time — or early.
- 4Explore the order screen
Learn where due dates, reschedule options and refunds appear before you need them.
- 5Read the fee screen
Know what triggers a fee so nothing on your statement is a surprise.

Open the app, enter your mobile number and type the verification code Sezzle texts you. Many users then enable Face ID, Touch ID or fingerprint login for faster access. On a computer, you can log in to your Sezzle account in a browser using the same phone-and-code method.

Fake Sezzle login pages and texts: how to spot them
Because the Sezzle app uses one-time codes to log you in, scammers often try to trick people into handing over that code. Anyone who has it can get into your account.
Red flags
- A text or email with a link asking you to “verify” or “unlock” your Sezzle account.
- A caller who says they are from Sezzle and asks you to read back a code.
- A login page reached from an ad or a message rather than the app itself.
- Promises of instant Sezzle Cash approval in exchange for an upfront payment.
What to do instead
Close the message and open the app directly. If something needs your attention, it will show up there. Contact support only through the help center inside the app or on Sezzle's official website.

“Set up your account for the long term: bank account as default, notifications on, biometrics on. That ten-minute setup is the foundation for higher limits and future Sezzle Cash eligibility.”

Can I use Sezzle without the app?
Yes, you can check out with Sezzle on partner websites and manage your account in a browser, but SezzleCash and the virtual card are managed in the app.
Does signing up for Sezzle affect my credit?
No. Sign-up uses a soft credit check that does not affect your credit score.
