Frequently asked questions
How do I know if my email has been breached?
With Data Shield you check your email against known data breaches (source: XposedOrNot): you see which sites it appeared in, in what year and which data was exposed.
Is it safe to check my password?
Yes: your password never leaves your phone or computer. Only the start of its fingerprint is sent (k-anonymity, Pwned Passwords) and the comparison happens on your device.
What should I do if my email is in a data breach?
Change the password of the breached site and of every site where you reused it, turn on two-step sign-in and be wary of emails and texts that mention the breach.
