The FTC and Department of Justice said that between May 2013 and September 2019, Twitter asked users for personal information to secure their accounts, but then used that information to target users with ads.
The complaint said users provided email addresses or telephone numbers based on Twitter’s “deceptive statements” that such information would be used for account security, like two-step authorizations.
The agreement also requires Twitter to improve its compliance practices.
Twitter did not immediately respond to a request for comment.
