- In order for "show password feature" to fully function in the Chrome browser, you have to know the "windows password" first before you can unhide it...
- Judging by your comment, I guess Brave browser allows its user to access passwords without layer protection, am I right [or you just don't use any passwords on your computer]?
I do have a pin as a security measure in my Windows 10 Laptop and I don't found any additional security measures / protection layer in accessing unhide autofilled passwords, as the browser always prompt users if a password that was inserted in a text field would be save for future password filling.
I've also tried it with Chrome (Brave is just an enhanced version of chrome FYI) but it worked the same. Do you have any proof with your argument?
