Does Duolingo support two-factor authentication (2FA)?

Duolingo does not currently offer two-factor authentication. Your password is the only lock on the account — make it long, random and unique.

Has Duolingo had a data breach?

In 2023, data from about 2.6M Duolingo accounts was harvested through an exposed interface (email addresses, names, and profile data) — no passwords were stolen. If you use the same password on other sites, change it — leaked passwords are tried against every major service.

Where do I change my Duolingo password?

You can change your password directly in your Duolingo account settings: https://duolingo.com/settings/profile
