Ubuntu Android Guide android setup

Setup pass on your Android

1. Setup git

sudo apt-get install openssh-client openssh-server
git init --bare ~/pass-repo
pass git init
pass git remote add origin ssh://oren@localhost:/home/oren/pass-repo
pass git push origin master

Explanation: these commands create a git repository that stores the encrypted passwords. The repository is located at ~/pass-repo and is needed in order to allow your phone to pull and push passwords.

2. Generate a set of OpenSSH keys

ssh-keygen -t rsa -b 4096
Enter file in which to save the key (/home/msfjarvis/.ssh/id_rsa): pass_store

Explanation: this command create two files: pass_store and pass_store.pub. Those are SSH keys that allow your phone to authenticate with your laptop

3. Copy the public SSH key to authorized_keys

cat pass_store.pub >> ~/.ssh/authorized_keys

Explanation: adding the public ssh key to the authorized_keys file will allow your phone (which will have the private key) to authenticate with your laptop

4. Setup your phone related stuff

• Enable USB Debugging on your phone (google for it. It depends on your Android)
• Connect a USB cable from your phone to your laptop
• Pick 'Transfer files' on the phone

5. Copy the private SSH key to your phone

sudo apt-get install android-tools-adb
adb push pass_store /sdcard/
adb shell chmod 644 /sdcard/pass_store

Explanation: adb push copy the private SSH key to your phone. /sdcard/ on Android is a symlink to internal storage so you can push to it without needing to poke into /mnt

6. Use the SSH key in the Password Store app

• Open the Password Store app on your phone
• Click on the three dots at the top right -> Settings -> Import SSH key
• Click on the three dots at the top right -> Show internal storage -> Click on the three horizontal lines on the top left -> Click on your phones icon
• Find the pass_store file and click it. Notice the message: 'SSH file imported'

Remove the key from your phone

adb shell rm /sdcard/pass_store

7. Connect the Password Store app to the git repository on your laptop

• Open the Password Store app on your phone
• Click on the three dots at the top right -> Settings -> 'Edit git server settings'

Fill-in the server info:

Username: my laptop's user
Server URL: my laptop's url
repo path: pass-repo

• Click 'SAVE'
• Click the left arrow at the top left
• Click on the three dots at the top right -> 'pull from remote'
