Keyboard doesn't appear on lock screen.

[An Idiot]

Hello, I have a Samsung s8 and I installed the latest update last night via the 'Install Overnight' option. When I checked this morning the update was done and it was asking for my password, however when I went to input the password, the keyboard would not show up. I restarted it however nothing happend. The keyboard won't show up at all. The power off button also doesn't work as it requires the password and, as said the keyboard will not appear. I know the password, the keyboard just won't appear. Please help.
@TFBisquit I can't make another post for some reason so edited to tell you that I rebooted like you mentioned but the keyboards still not appearing.

Press and hold volume down + power button for at least 8 seconds. That will reboot your device and hopefully correct the keyboard not appearing.

He's got an S8, so no home key. I'm still trying to find the instructions for it.

Here you go, Bixby+volume down+power

What will a cache wipe do? Will things be deleted?

So I did the cache wipe partition but the problem persists.

Factory reset is your next step. In the same menu as wipe cache.
If that also fails you're looking at an Odin flash of either nougat or Oreo.
As a last resort you could visit a Samsung service center, and let them reflash it. If that fails it would seem to be a hardware issue, where the keyboard sensor isn't working anymore. Then it needs to be repaired.

PS. A bit late but next time better to do the upgrade manual, or at once when downloaded, with a fully charged battery and/or connected to your power charger.

PS2. You can shut down the device from that same menu also. Then after some 15 minutes you can reboot it, and maybe that will do the trick?

You could also try connecting a basic USB keyboard via a USB-C to USB-A cable. I've never tried this myself -- with phones that have a microUSB-A port, you'd need an OTG adapter (very inexpensive0, but I'm guessing OTG wouldn't be necessary with USB-C?

A physical keyboard would at least get you past the screen lock. Then you could try installing another keyboard app, or get to the settings and try clearing the current keyboard app's cache/data.

Another thing to try is to boot into Safe Mode and see if the keyboard comes up then: https://support.t-mobile.com/docs/DOC-34283

With the S8 and later you replace the home key with the Bixby key

I tried turning the power off then rebooting and using safe mode, both didn't work. I guess USB keyboard is the next step, I'll see if I can find one near me.

Could anyone here recommend a cheap micro USB keyboard so I can try this solution out?

Is your S8 tied to a carrier? If so, try taking it to a carrier's storefront and see if they can loan you a keyboard for 15 minutes.

Or, if you're in the US, bring it to a Best Buy, and ask the Samsung Experience rep if he or she can help.

So it took a long time because of [reasons] but I finally have an otg cable and used it to connect an old USB keyboard we had to my mobile but it didn't work.

 

[TFBisquit]

Factory reset. Or repair by a Samsung service center which will also factory reset your phone.

I had the same problem. Resetting factory defaults was not an option because i had too much data on the device that I wanted saved before I do the reset. My solution;

1. Buy an OTG cable (circa USD 4)
2. Use OTG cable to connect samsung device to a PC keyboard
3. Use keyboard to login
4. Go to settings and remove lock screen protection
5. Backup all my data to external devices
6. Save all my contacts and send as email to 3 of my many email accounts
7. Reset factory default
8. Samsung keyboard now working and have restored all my stuff.
