MyPwd offers an extensive database that can be easily accessed to discover any password needing to be changed before it can be used in frauds perpetrated by cybercriminals. MinhaSenha.com is the Portuguese version and MiContrasena.io is the Spanish version.
Using MyPwd, i found out that my password was leaked and i was able to change it in time, before some cybercriminal stole my email account.
The problem is that I used the same password in several applications.
I had to change everything.
The cool thing is that now it is monitoring if my email is compromised in any new leak and, if that happens, I am alerted quickly.
The main difference from haveibeenpwned? is that MyPwd also shoed me the leaked password, not only the email. So I don't have to change my password in every single login i've ever made, just those I used the leaked password
