upload known breached default or standard passwords
Many applications use your API to detect known vulnerable passwords. In this regard it would be great to have some way of uploading known default passwords, e.g. company "standard" passwords or vendor specific device passwords. This would help to prevent users from choosing old and compromised "standard" passwords.
The intention for Pwned Passwords is to be just that **pwned** so things that have been seen in previous breaches. That almost certainly includes many default passwords, but it's not something we'd seek out and add if they haven't previously been breached.
