My point is, as a broad-based message, as soon as you start saying complicated words like "browser" and "validate domains" and "credential" and "password managers," nontechnical eyes immediately glaze over. I think your advice works for the most technically inclined 25% of users. It just confuses the rest.
"Don't click links," despite having more false positives when used as an individual's safety heuristic, resonates more and thus will result in many fewer false negatives when applied to the general public. The cost of a false positive is relatively low, while the cost of a false negative is high.
The phishing site immediately gets their domain ntlm hash, which can often be cracked to gain a password.
This can also be a problem in PDF and Word docs without the need to employ a 0 day. https://resources.infosecinstitute.com/steal-windows-login-c...
Also to note that password managers can help mitigate phishing, as they will not offer to complete passwords if the domain does not match.
