mSecure is urging customers of its password manager to act to protect the confidential information stored in the app. The company may ask users to change passwords, reset two-factor authentication (2FA), and remove passkeys.

The warning came in an email sent on November 3 in the name of developer mSeven Software. The email says the company recently learned of suspicious activity linked to the app. The source excerpt ends before it describes that activity in full, so the nature, scope, and cause of the activity cannot be confirmed from the material provided.
