As has been discussed on previous ToWs, one of the notable features of the Windows 10 Anniversary Update has been the slew of improvements that have come to the default web browser, Microsoft Edge. Even Thurrott is talking about it, if anyone is prepared to pay to read.
The availability of extensions is surely one of the big news items. One of the most useful extensions (see the rest here, or in the store) is LastPass – an online website password manager, useful for a couple of things … keeping an off-machine archive of your usernames/passwords for websites (across multiple machines if you pay for a Premium subscription) and an easy way of entering the saved username & password (look for the ellipsys icon which the addin shows at the far side of password dialogs – click on that to select the saved usernames & passwords for that site; you could use this to manage multiple identities for the same site).
The LastPass addin – and corresponding web service – also lets you set up a random password when signing up for new websites; hopefully avoiding the same username/password problem that hurts when online forums or websites get compromised and usernames & passwords are leaked. And who has the time to generate and remember a unique username & password for every site?
