Hi lyndaraz,
It sounds like you're seeing a message that passwords have been compromised on your iPad, and want to help.
Just to make sure we're on the same page, can you let us know more about where you're seeing that alert? For example, are you seeing it under Settings > Passwords > Security Recommendations?
If you're using iPadOS 14 or later and you're seeing that alert under Settings > Passwords > Security Recommendations, it sounds like the Detect Compromised Passwords feature may be enabled.
"iPad also securely monitors your passwords and alerts you if they appear in known data leaks. If you don’t want iPad to perform this monitoring, go to Settings > Passwords > Security Recommendations, then turn off Detect Compromised Passwords."
More about that, and how to change compromised passwords here: Change a weak password on iPad
Take care!
