Cryptfs Password Manager
Android device encryption password manager app. Lets you changes the Android disk encryption password. Essentially the same as
Code:
# vdc cryptfs changepw <newpassword>
but easier to use and slightly more foolproof. Requires root access.
WARNING
If you forget the new password after you change it, you will not be able to boot the device. You will have to perform a factory reset, DELETING all your data. Make sure you take a full backup before using this tool, and REMEMBER THE PASSWORD. You have been warned, use at your own risk!
Why and how to use this
Android 3.0 (Honeycomb) introduced disk encryption and it has been available on all subsequent versions. It encrypts the data partition with a key protected by a user-selected password and requires entering the password in order to boot the device. However, Android uses the device unlock password or PIN as the device encryption password, and doesn't allow you to change them independently. This effectively forces you to use a simple password, since you have to enter it each time you unlock your device, usually dozens of times a day. This tool allows you to change the encryption password to a more secure one, without affecting the screen unlock password/PIN. To change the device encryption password simply:
Enter the current password (initially the same as the unlock password/PIN)
Enter and confirm the new password
Hit 'Change password'
The changes take effect immediately, but you will only be required to enter the new password the next time you boot your device. Make sure you choose a good password, not based on a dictionary word, since automated tools can brute force a simple password in minutes. Above all, make sure you REMEMBER the new password.
If you change the device unlock password/PIN, the encryption password will be automatically changed as well. You need to use this tool again to change it back, if required.
Once Android adds an official way (system UI) to change the passwords independently, this tool will no longer be needed. Star this issue if you want this to happen:

I want to change my lock screen type to pattern but I cant click it! It says: "Disabled by administrator, encryption policy, or credential storage."
Help!
Looks like there's an app that has upped the security level. Check under Settings --> General --> Security --> Device Administrators. It should only list KNOX and Android Device Manager (if you enabled that).
In your another thread u said u encrypt your phone right? If you read encryption rule u will not ask such a question over here, once u encrypt u have only one option to lock your phone.

Is it possible on miui to change sim card pin?
Can't find option to do so.
on Redmi Note 4 (MIUI8)
1. In System Settings tap Additional Settings
2. Enter Privacy
3. In Security section tap on your SIM Card name it will simply be name of your mobile provider
4. Now using Lock SIM card you can choose if phone should ask for PIN to unlock the SIM Card after each reset and Change SIM PIN option to change or set new PIN code.

Might be redundant to question, but you're logging in with the same credentials you used to request the unlock?

Did you unlock Developer mode?
Did you enter your Mi account credentials under the Developer settings entry?
To unlock Dev mode, tap on the MIUI Build entry under "About Phone". You have to tap it 7 or 8 times.
Then when you go back out to the Settings menu, under Additional Setttings, you'll see Developer Settings. In the Developers Setting area you'll see Mi Unlock or something like that. Enter your credentials there
Under developers settings ist dont have this settings... I have Under MiAccount My Email My Number Name etc...

I don't see that entry, and I didn't have to do that to unlock my Mi Mix.
To the OP, in about phone, what does it say for Model number and MIUI version?
Yes i have activated developers... And Mi account credentials dont See in developers
I have the same problem. From my understanding you need to apply to unlock your device first in order to have that bind MI account in developer option. I just applied and they said it might take to 10 days to get approved
Bootloader unlocking
I don't want to argue the issue:
here is what I DID.

Please make sure you're on official MIUI ROM to unlock
What you should do after received the approval SMS?
1) Settings---> About phone---> MIUI Version (Tap on it to enable developer option).
2) Settings---> Additional settings---> Developer option and bind your approved Mi account under Mi Unlock Status. This works on latest China & Global Stable and Developer ROM. For those who don't see this option please check out next tutorial and unlock in Developer ROM
I hope this helps, because for me it did
Cheers

So you received the SMS indicating permission to unlock?
And you entered the same credentials (login or MIUI ID number or cell phone number and password) you used to create MIUI account and request unlocking permission?
J

i Log in to the Unlock Tool with my phone number ..the curios mistake was my number is ...0151******* my country Germany ...+49
in Germany must i write +49151*******
