When we prompt our browser to save credentials once we log into a web application, they store our corresponding username and password. I know to recover these things from my browser. But I want to know to which directory in Ubuntu these passwords are stored?
Chromium and chrome
Store passwords in three ways:
- GNOME Keyring
- KWallet 4
- plain text
Chromium chooses which store to use automatically, based on your desktop environment.
Passwords stored in GNOME Keyring or KWallet are encrypted on disk, and access to them is controlled by dedicated daemon software. Passwords stored in plain text are not encrypted. Because of this, when either GNOME Keyring or KWallet is in use, any unencrypted passwords that have been stored previously are automatically moved into the encrypted store.
The manual page for google chrome (
man google-chrome) shows:
--password-store=<basic|gnome|kwallet> Set the password store to use. The default is to automatically detect based on the desktop environment. basic selects the built in, unencrypted password store. gnome selects Gnome keyring. kwallet selects (KDE) KWallet. (Note that KWallet may not work reliably outside KDE.)
Chrome uses the same method as Chromium. And you can use above setting to switch to plain text passwords (not recommended of course).
Chrome (older versions)
Passwords are stored in
~/.config/google-chrome/Default/Login\ Data and that is a sqlite database file (that file is encrypyed).
This login database file is in SQLite format which is lighter version of popular SQL database. In addition to login credentials it also stores other information such as auto complete entries, IE7 Logins, search keywords etc. The 'logins' table is where all the login or sign-on secrets are stored by Chrome. This table contains following interesting fields
Origin_URL - Base URL of the website Action_URL - Login URL of the website Username_element - Name of the username field in the website Username_value - Actual username Password_element - Name of the password field in the website Password_value - Encrypted password Date_created - Date when this entry is stored Blacklisted_by_user - Set to 1 or 0 based on if website is blacklisted or not.
Except the password field all other fields are entered in clear text. The password for all stored websites is encrypted using Triple DES algorithm seeded with logged on user's password. That means login secrets cannot be decrypted across the user or system boundaries unless under certain conditions.
Your passwords are stored in the key4.db and logins.json files.
