Stop fingerprinting your users. It is a violation of privacy.
Your website is listed in a Washington Post article about how companies are increasingly fingerprinting their users' devices to track them. You should end this practice. It is a violation of the privacy rights of every one of your users.
Probable proof of fingerprinting: I just logged in using Chrome, which I never use to check (my mostly junk) email account on Yahoo--so I haven't needed to log in before. Yahoo made me verify the device.
In the meantime I will be working to transition my email account to another, more trustworthy provider, and I will no longer browse the (increasingly ****** tabloid article) content provided by Yahoo.
