[FIX 2021] Authentication is required when the PC wakes from sleep

There is a very fantastic feature in Windows 10. If you are not using your computer, Windows will automatically put your computer in a low power state and turn off the computer screen. But many users have been facing the problem where Authentication is required when the PC wakes from sleep.

Basically, it means, after they put their computers to sleep, when they turn them back on, Windows will prompt them to enter the password to log in (authentication).

I just hope this gets resolved in the upcoming Windows 11!

So in this guide, we will see how to…

But before we start, I want you to understand some of the Windows sleep mode features (although you can go down Scroll directly to the solution) 

What is Windows sleep mode and how does it work?

Have you noticed that your phone’s screen will automatically turn off when you do not use your smartphone for more than 30 seconds or a minute?

But when you turn on your phone again, all your applications and processes are still open as before. 

Sleep mode has precisely the same function in Windows. Sleep mode can help you save power when you are not using it.

According to Microsoft: Sleep mode consumes very little power, and your PC starts faster and immediately returns to where it stopped.

You don’t have to worry about losing your work due to battery drain. If the battery is too low, Windows will automatically save all your work and shut down the PC.

Use sleep mode when you want to leave the PC for a while, for example, during a coffee break.

For many PCs (especially laptops and tablets), your PC will go to sleep when you close the lid or press the power button. 

Isn’t this a fantastic feature?

Although this is a fantastic feature, the problem that many Windows users face is authentication is required when the pc wakes from sleep, which means,

when they put their PC or laptop into sleep mode and then wake them up, it prompts them to enter a password.

Now let’s see how to…
