PSA. Don't share your password in your app's release notes

Excited to watch the Guardians of the Galaxy Vol 3 at the cinema, or see what all the fuss is around The Super Mario Bros Movie?

Maybe you’ll leap onto your smartphone, and click on the MyOdeon app to find out what films are playing at your local flicks.

Oh! The OdeonUK app has just been updated… I wonder what new features it has?

Password: Odeon1234!

Err… that looks awfully like the credentials for a test account, and – if I’m not very much mistaken – “Odeon1234!” is a really very dumb password indeed.

My guess is that this username and password combo was supposed to remain private, and only used by Odeon’s internal technical staff – rather than shared with hundreds of thousands of movie buffs.

Hopefully there’s no serious harm done by this, but all app developers should take care about what they post in their release notes – just in case it accidentally leaks any helpful information to ne’er-do-wells.

Hat-tip: Thanks to Fiasco on Twitter for bringing Odeon’s curious release notes to my attention.
