This is a hard one. So the first hurdle that I came across is with the font used for the padlock's brand. My best guesses so far have been "Elsses", "Elzzes", or "Elcces", but that doesn't really turn up anything useful. This doesn't surprise me much, though, because looking at the font of "Top Security" tells me that this is probably a pretty simple lock from a Chinese manufacturer. Given that it's probably a basic 5-pin pin-tumbler lock loaded up with standard pins, which as you can probably imagine conflicts a bit with the "Top security" statement on the face of the lock, but that's a typical thing these manufacturers do.

I also wouldn't be surprised if the shackle was made from regular non-hardened stainless steel. It's also likely that it used a regular latch on the inside instead of a ball-bearing, thus making it vulnerable to shim attacks. These two points being the most important since thieves will typically gravitate towards the quickest and easiest ways to get past security instead of taking the time to learn how to pick.

In the end, it's an image that I see has been used for a number of posts and articles relating to security online. I wouldn't be surprised if the manufacturer didn't even exist anymore today.

Oh. Sorry, you were asking about password managers. I guess I got a little distracted. I use BitWarden. It's pretty good.
