DESCRIPTION
db.login sets login parameters such an user name and optionally also a password, a hostname or a port for the connection to the selected database through the DB driver.

NOTE
Options host and port are related to only SQL database backends like PostgreSQL, MySQL or ODBC.

Note that the passwords are stored in a hidden, unencrypted file in the user account, specifically

    •   in the ’home’ directory, i.e. $HOME/.grass7/dblogin (Unix-like systems)

    •   %APPDATA%/GRASS7/dblogin (MS-Windows)
Only the file owner can access this file.

EXAMPLES
Only username specified (assuming locally accessible PostgreSQL DB without password):

db.login driver=pg database=mydb

Username, password and hostname specified (note that the command lines history will store the password in this way):

db.login driver=pg database=mydb user=bacava password=secret host=db.example.com

Username and empty password specified:

db.login driver=pg database=mydb user=bacava password=""
