Lastpass Suddenly has a Site it says is insecure

This is strange. I am using Windows 10 Pro and Chrome Version 81.0.4044.138 (Official Build) (64-bit). This is on 2 systems and all of a sudden 1 system shows "We have Detected an Insecure Login Form" on ONE site that the Other system shows as OK. This is the same Lastpass user ID so why would 1 system not like it for this ONE site. This used to be OK! The other sites on this "bad" system are all OK.

Not sure where to look to fix this. I do not want to change Lastpass as it is fine on the other system!

Check that the URL shown in LastPass points to https

If it starts http it suggests that one of your browsers doesn't redirect to https.

Just a guess.

Yes, it is HTTPS and both systems use Chrome and the other sites are https, so the browser does respond to https.

One system likes this and the other does not.

Found this but I don't really understand about those protocols.

Why am I seeing the message, "LastPass has detected a login form that is insecure" when I visit a site?

Check if both browsers have identical updated addons and matching security or other settings.

Maybe one browser has a script blocking or ad blocking extension that the other one doesn't.

Try another portable chromuim based browser and install LastPass and if login works then it's a browser problem.

Vivaldi Browser Help | Using a standalone version of Vivaldi

SRWare Iron - The Browser of the Future - link for portable is down towards the bottom of the page.

i meant to suggest running a chrome variant with LastPass extension installed on the machine with the problem.

If it works okay on the portable browser I'd suggest a clean install of Chrome.

If you get the same problem then something else is the culprit.

Will check back tomorrow or other members can help. Personally I don't actually use chrome but do use chrome variants.

OK, I will look at the extensions on the 2 chrome browsers. As I said it is only 1 site with this issue on this ONE system.

So on that system get a portable chrome variant and run it. Install LastPass extension in the variant and test to see if you get the same problem.

OK, but I want to see if all all the addons on both systems are the same. OH is Vivaldi the portable Chrome based Browser you were mentioning that I should try? Is that the best?
