Device encryption using lock screen password - Xiaomi Mi 9 SE Questions & Answers

Hi,
I have Mi 9 SE with global rom v 10.2.2.0(PFBMIXM).
When I go to system settings->Additional settings->Privacy->Encryption & credentials, it shows that my device is encrypted. But in the past on other xiaomi phones I owned there used to be an option "Encrypt Device with lock screen password" which is missing in MI 9 SE.
So, in the past the phone used to ask for lock screen password during boot and only then then system/data disks would be decrypted and phone would start booting. Now this is not happening because the phone is using whatever device default password it has for decrypting the device during boot up. So I have following questions,
1) Can someone with above version of global rom confirm that they also do not have "Encrypt Device with lock screen password" option?
2) Can we also confirm if China and EEA Roms are also missing these options?
3) Is there any possibility of somehow enabling the "Encrypt Device with lock screen password" because I would really like to use my password for encryption rather than some device default password.
Many thanks in advance for your help

There is no way doing this and it's this way on all ROMs.

How do i check if my phone is encrypted?

With Samsung devices, turning on device encryption force you to use 6 characters password (alphanumeric), which is troublesome if you use your phone often.
What I found out is that after I set such password, complete the device encryption and go back to the Lock Screen setting, I can change the password to 4 digits.
Going back to encryption setting, it said I can now encrypt the device, but must use 6 characters password. But isn't my phone already encrypted? AFAIK, there is no turning off encryption once it's done.
So at this point, is my phone encrypted or not?

The phone is encrypted but like you said you cannot permanently decrypt the phone once the process is completed.

Thanks for the info.
I am curious why initially the device requires alphanumeric passwords (which I created), but once encryption is done, I can go back to the "Lock Screen" and change it to just numeric password. I believe this will NOT remove encryption, but for confirmation, want to check if the encryption is still there.

I had to un-encrypt my phone by unrooting via Oden. Once i Odened then you have to do a factory reset and you are un-encrypted for good.

Disable On Boot Password

Hello everyone, I'm a newbie to the OnePlus world.
So my question is: how can I disable the password that is required before android is launched on my OnePlus 3 ?
I've searched accross xda but I found nothing, sorry if this has already been answered.
In the beginning I found it very useful, but once I removed Google Keyboard, I was not able to enter that password.
I want to use a modded google keyboard (with number row), and on the xda thread, the dev ask to remove the defaut Google Keyboard.
Regards.
Go into Settings > Security & fingerprint > Screen lock and remove it (choose None).
Once the device is set to none, go back into Settings >Security & fingerprint > Screen lock and choose PIN. It will ask you here if you want secure boot (enter a PIN to start device) or not use it. Just choose the latter.
EDIT: If you have fingerprint set up, you will lose it during this process
Another option is to just switch between password, pin or pattern. You still get the option of not to set on boot, but this prevents the fingerprints to get deleted as they do when switching to swipe or none.
Thanks guys the problem is now solved, I've selected PIN with NONE as option for boot.
I can't do anything else because would like to remove the google keyboard.
To do so you will need to wipe your /data but its possible through twrp for excample. Simply after hard reset chose not to require password after boot
I'm confused as to why Google Keyboard is required for entering a password. Can't you just set your other keyboard to be the default?

[SOLVED] Encrypted but no need to enter password

Hey guys,
I have always had my op3 encrypted and I've become used to always entering the pin when booting up, accessing twrp etc. but today when I rebooted into twrp I didn't have to enter any pin to use twrp. When booting up the system I didn't have to enter a pin either.
When I check the settings under Security & Fingerprint it looks as in the attached screenshot, I don't have any options to decrypt or anything either
I'm running OOS 4.1.3, FrancoKernel #23 , Magisk 12, twrp-3.1.0-x_blu_spark_v27.
Is this something that anyone has experienced and know how to fix?
I want to keep my encryption but then, of course, you should have to use the pin.
Cheers!
Then the pin is defaulted and thus you don't need any. I don't need one, too and never did, but all is encrypted (Even locked down with a pin on bootup and fingerprint otherwise)
I believe this is an option you need to setup during the wizard when you initially set up the device. It asks you whether you want to require a pin on startup or not.
But, you can also turn this on by going to settings>security>screen lock.
From there, you click on the area where it says PIN. Confirm your pin, then click PIN again, and there should be an option to require pin for startup. Other than that, you are still encrypted, but it is all bypassed in order for quicker startup.

Ah that was it! it had somehow disabled itself, simply going in and enabling "require pin to start device" solved it.
Thanks!
Try removing the lock screen password and setting it up again and it will be back again in twrp.?

Can I use alphanumeric decrypt password?

In MIUI it only has the option to use the lock screen PIN to encrypt the data partition. I know I can change the encryption password to something different manually, as described here
https://www.xda-developers.com/how-to-manually-change-your-android-encryption-password/
However when MIUI boots it only seems to allow users to enter a numeric decrypt password. I prefer to use an alphabetical or alphanumeric, as I find it less confusing using one PIN (for the lock screen) and an alphabetical or alphanumeric password for decryption and they're also longer and thus more secure than a 4 digit PIN.
Is there a mod for MIUI that will allow me to enter a alphanumeric decrypt password at boot?
Is no-one else bothered by this? Does everyone just use the same PIN for decryption and lockscreen? This seems like bad practice because if someone sees you enter your lockscreen PIN, they will then be able to unlock/decrypt the phone even after it is turned off or the battery runs out.
I've also found with the Note 5 the decrypt PIN screen on boot is very dim, making it more difficult to enter the PIN that it needs to be. My Note 4 isn't like this. I have Redfox Recovery on my Note 4 and OrangeFox on the Note 5 but I wouldn't have thought that would be causing this.

Different device encryption password than screen unlock pattern/PIN/password

Hello,
It's possible with the last version of LineageOS, to have a different device encryption password than screen unlock pattern/PIN/password ?
Like this old APP : https://github.com/xmikos/SnooperStopper
SnooperStopper allows you to have different device encryption password than screen unlock pattern/PIN/password. You can have strong device encryption password (which you only need to enter once after booting your device) but simple pattern/PIN/password for unlocking your screen.
