How do I open my locked tab secured by a password

[peerless cucumber]

So the battery in my galaxy tab E was 100 and it kept dying quickly so I had turned on ultra power saver mode. What I forgot was that previously my Samsung keyboard wasn't working so I had installed a random keyboard n it was functioning just fine with it. Now I even forgot to select the keyboard app in the selected working apps. To top it all, my tab is secured with a password. How do I open my tab...
Does the ultra power saver switch itself off when the battery dies?

It should, but you can always try to use the Bixby button for dictation or try to select a different input method (i.e. the stock keyboard app that shouldn't be put to sleep). Additionally you can try booting up your device into Safe Mode.

Welcome to Android Central! I moved this from the Galaxy Tab forum (which is for the ancient original Galaxy Tab) to the More Samsung Tablets forum, since we don't have a specific one for the Tab E.

Another option is to connect a basic USB keyboard using an OTG adapter.

You don't remember your password? Keyboard doesn't pop up?

Most likely going factory reset in recovery

I believe OP knows their password, but is unable to enter it because no keyboard option comes up on the lockscreen.

Either way looks like going factory reset in recovery , out of all these types of question from forgotten password or keyboard not showing up resulted in usually factory reset in recovery , they can try safe mode slim chance but worth a try , external keyboard but need to open the phone to enable , bixby or Google dictation needs phone unlocked also .

The scenario I'm thinking of is to connect a USB keyboard via OTG just to enter the lockscreen password, and if that work, then go to Settings>Apps and look for the keyboard app to make sure it's re-enabled.

It might work, but I think u might have to give it permission but can't say 100%

Unless it's a recent change to Android you don't need permissions to use a mouse or keyboard, I used to do it all the time with phones that had damaged screens.

You bring up a good point I'm thinking they have a current Andriod device with all its new permissions but they might have a shot at it being on a older Android version.

Yeah. That seemed to work! Thanks a lot everyone!
