With LessPass, you can automatically log into all your sites using generated passwords for social networks, emails, servers, and more. It includes a handy keyboard shortcut (Ctrl + Shift + L) to quickly launch the extension, making password management seamless and hassle-free.

Is lesspass Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

lesspass does not require any sensitive permissions.
