Update after the QA specification
It seems that at present google chrome do not provide a way to fully export in plain text the list of password, stored in an sqlite3 database on the hard disk... but we do not resign so fast.
It seems even that it exists a method when chrome is synchronized with the google account (Make sure that you have ticked Passwords in Advanced Sync Settings). You need also sqlite to read the database.
Start chrome with this option to have the database saved in plain way with the name Login Data
google-chrome --password-store=basic
"Wait for a while until the data is synced (type chrome://settings/passwords
in your address bar to make sure your passwords are showing):
Close all the Chrome windows and export the table in text from the database
sqlite3 -header -csv -separator "," ~/.config/google-chrome/Default/Login\ Data "SELECT * FROM logins" > ~/Passwords.csv
Notes:
- for Google Chrome:
~/.config/google-chrome/Default/Login Data
- for Chromium:
~/.config/chromium/Default/Login Data
