I use a password manager and create very long passwords where possible, including for my Google account. The problem? when setting up a new Android phone, I can’t download the password manager app until I’ve logged into my Google account, which is nearly impossible without the password manager app.
The workaround? Enable USB debugging on the phone, and use ADB to enter the password:
./adb shell input text "LONG COMPLICATED PASSWORD"
Is it safe enough? Probably not. Use at your own risk 🙂
