Icon for unmasking passwords (open or closed to begin with)?

The commonly used icon for showing passwords is the eye icon which when clicked shows the passwords as given below

enter image description here

However since the concept of revealing passwords is still unknown, a simpler approach might be to just use a checkbox to reveal the password

enter image description here

This can be easily understood by users.

To quote this article


Another approach is to provide a checkbox for unmasking. Thus, when
the user types their password, it is masked, but when they check the
box, it gets unmasked, allowing them to see whether they’ve made a
typo. A little more effort is required with this approach with the
checking and unchecking, but it’s far better than a
password-confirmation field because it enables users to see and fix
their typos with ease.

enter image description here

Another advantage is that users can check the checkbox as long as needed to allow them to read the password at their leisure while with an icon you have to keep it pressed and hence the user has to keep on interacting with it.

Another advantage is that its accessible to screen readers as users can quickly understand what checking the checkbox does.

Creating my own 2FA? [closed]

I’m looking to code my own 2 factor authenticator as a project for my computer networks class. I don’t need anything too fancy or safe because this is not going to be used anywhere. I’m supposed to use C/C++ for the code, but I can also use Android studio. I’m looking for general pointers as to what to research and where to begin.

suspend – Ubuntu 18.04: Screen not turning off or suspending when the lid is closed

I hope you’re well! I’ve been having an issue with my laptop, a Dell XPS 13 9370 running Ubuntu 18.04, where the screen does not turn off nor does the system suspend when the lid is closed. My laptop spends a lot of time in my backpack and this issue can cause the laptop to grow very hot very quickly. I’ve tried the solution using systemd, I’ll paste the complete file from systemd/logind.conf below. However, this still isn’t working for me. Does anyone have any ideas?

oa.operator algebras – Sufficient conditions for a map $phi: M(A) to M(B)$ to have strictly closed image

Let $A$ and $B$ be $C^*$-algebras with multiplier algebras $M(A)$ and $M(B)$. Are there any nice conditions that ensure that a strict (= norm-continuous + strictly continuous on bounded subsets of $M(A)$) linear map $phi: M(A) to M(B)$ has strictly closed image. In particular, I’m interested in the following situations:

(1) $phi$ is a strict $*$-morphism.

(2) $phi$ arises as the unique extension of a strict linear map $A to M(B)$.

(3) $phi$ arises as a unique extension of a strict injective linear map $A hookrightarrow M(B)$.
