ORAPWD
You can create a password file using orapwd utility.
Users are added to the password file when they are granted the SYSDBA or SYSOPER or SYSASM privilege.

The Oracle orapwd utility assists the DBA while granting SYSDBA, SYSOPER and SYSASM privileges to other users. By default, SYS is the only user that has SYSDBA and SYSOPER privileges. Creating a password file, via orapwd, enables remote users to connect with administrative privileges.

$ orapwd file=password_file_name [password=the_password] [entries=n] [force=Y|N] [ignorecase=Y|N] [nosysdba=Y|N]

Examples:
$ orapwd file=orapwSID password=sys_password force=y nosysdba=y

The following describe the orapwd command line arguments.

FILE
Name to assign to the password file, which will hold the password information. You must supply complete path. If you supply only filename, the file is written to the current directory. The contents are encrypted and are unreadable. This argument is mandatory.

The filenames allowed for the password file are OS specific. Some operating systems require the password file to adhere to a specific format and be located in a specific directory. Other operating systems allow the use of environment variables to specify the name and location of the password file.

PASSWORD
This is the password the privileged users should enter while connecting as SYSDBA or SYSOPER or SYSASM.

ENTRIES
Entries specify the maximum number of distinct SYSDBA, SYSOPER and SYSASM users that can be stored in the password file.

FORCE
(Optional) If Y, permits overwriting an existing password file. An error will be returned if password file of the same name already exists and this argument is omitted or set to N.

IGNORECASE
(Optional) If Y, passwords are treated as case-insensitive i.e. case is ignored when comparing the password that the user supplies during login with the password in the password file.This becomes more important after 11g release as password become case sensitive in that release
