It is not hacking any password if it doesn't involved any password cracking or brute forcing. Saved passwords is already "
Saved"
then using such html tags isn't necessary. Also, browsers do already have the feature that shows you all saved passwords in it.You could see it in Settings > Additional Settings > Auto-fill > Passwords > then click on the unhide icon beside the password saved. (I use Brave browser and this is the process of showing saved passwords)

- 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]?
