How to Save My User Account and Password in Google App Engine Launcher?

Question

I'm using the Google App Engine Launcher to deploy my app to the GAE servers. Is there a way to save my user account and password so I don't have to type it in every time I redeploy?

I'm still in the learning stages of using GAE so typing my 16 odd character password gets tiresome when I redeploy 15+ times per evening.

Maybe you have a reason to deploy but there is a local server with the SDK. — ide, Mar 01 '11 at 02:46
I redeploy to work with my live data. I'm the only one who uses the app so I'm not really risking a lot by working on the live version. =) — Ken, Mar 01 '11 at 02:54
OT FYI: You can download your live data to your development server with the python bulkloader tool. It works even with Java. — Riley Lark, Mar 01 '11 at 02:58
I use AutoIT and it works very good. The solution is here: http://stackoverflow.com/questions/17527767/scripting-gae-launcher-with-autoit — Niklas Rosencrantz, Jul 08 '13 at 15:17

You can make a .bat file that has the following text:

echo <password> | c:\python25\python.exe "C:\Program Files\Google\google_appengine\appcfg.py" --email=username --passin update <directory of app on your pc>

(According to GAE docs you cannot specify the password as a command line option)

Oops. BTW I'm using 2.6 and everything is okay so far. – Uri Apr 29 '11 at 08:45
@ZuzooVn please be more specific, what details do you need? – Uri Oct 27 '11 at 12:31
You are my hero! the "echo | " part is genius! :D – Mark van Straten Apr 24 '12 at 14:04
Quite insecure. [Stuart Langley gave a much better answer](http://stackoverflow.com/a/11964110/94363) – rds Dec 30 '12 at 14:57
Much more secure idea is to turn on two-factor authentication and use: appcfg.py --oauth2_refresh_token=token update yourapp/ – Thronk Feb 08 '13 at 15:31

Use oauth to save an OAuth2 token so you don't need to keep re-typing your password.

I changed the answer to this because oauth is (two years later) the preferred method currently. Oauth + a bat file to upload works great. – Ken Jul 16 '13 at 19:43

This answer lacks practical advice on how to use OAuth with GAE – David Yell Mar 05 '15 at 10:59

The accepted solution didn't work for me. Using pipes did

echo <password> | c:\python25\python.exe "C:\Program Files\Google\google_appengine\appcfg.py" --email=username --passin update <directory of app on your pc>

Other tips & trick: using command line as below:

To get appcfg.py to accept --password on the command line instead of being prompted for it:

Change: *appengine/google_appengine/google/appengine/tools/appcfg.py*

add the following in the parser.add_option section:

parser.add_option("-p","--password", action="store", dest="password",
                  metavar="PASSWORD", default=None,
                  help="The password")

Then modify the GetUserCredentials function:

def GetUserCredentials():
  """Prompts the user for a username and password."""
  email = self.options.email
  if email is None:
    email = self.raw_input_fn("Email: ")

  password = self.options.password
  if password is None:
    password = self.raw_input_fn("Password: ")

#      password_prompt = "Password for %s: " % email
#      if self.options.passin:
#        password = self.raw_input_fn(password_prompt)
#      else:
#        password = self.password_input_fn(password_prompt)

  return (email, password)

That's it, now you can call:

appcfg.py update demos/guestbook --email=email@gmail.com --password=xxxx

I just wanted to say thank you to Friar Broccoli, it's exactly what I was looking for. To clarify for other beginners like myself, my final batch file ended up looking like the following,

c:\python27\pythonw.exe "C:\Program Files (x86)\Google\google_appengine\appcfg.py" --oauth2 update "C:\Users\[username]\[directory]\app.yaml"

Worked perfectly, wish this solution was higher up.

You're a beginner so I'm assuming you've done research into this, but is there a good public demo project for GAE that isn't horribly outdated and also includes things like bat files for uploads? If there isn't then I'll make one. – Ken Nov 17 '14 at 23:00

appcfg already does this for you. Per the docs:

appcfg.py gets the application ID from the app.yaml file, and prompts you for the email address and password of your Google account. After successfully signing in with your account, appcfg.py stores a "cookie" so that it does not need to prompt for a password on subsequent attempts.

If this isn't occurring for you, you might want to try deleting any .appcfg* config files.

The cookie gets wiped after a reboot or a few hours of inactivity. – Matt Mar 01 '11 at 07:16

In one of my computers this works, in other it doesn't. I couldn't find any `.appcfg*` config files. – fiatjaf Jul 01 '13 at 23:53

It's amazingly simple. Just put this in a batch file:

appcfg.py --oauth2  update  "X:\local\path\to\your\app.yaml\file"

The first time you run it google will authenticate, after that it's all automatic.

You could write a command line script that executes appcfg.py to do this.

You can specify the email to use with the --email= command line parameter.

You can pass in the password from stdin by using the --passin parameter.
