CGA Fitting Reference. A CGA fitting is the standardized system for the attachment of a compressed gas cylinder to the required regulator or transfer line. Examples of CGA fittings would be CGA-580 for Non-flamable, Non-oxidizing gasses such as Nitrogen, Argon, or Helium. CGA-590 is used for compressed air and CGA-326 is used for Nitrous Oxide.
Google Authenticator is a mobile security application based on two-factor authentication (2FA) that helps to verify user identities before granting them access to websites and services.
In most cases, the extra authentication is simply a numeric code; a few digits sent to your phone, which can only be used once. More and more services support a specialized app on the phone called an authenticator, which will do that same job. The app, pre-set by you to work with the service, has a constantly rotating set of codes you can use whenever neededâand it doesn't even require a connection. The arguable leader in this area is Google Authenticator (free on Android, iOS, and BlackBerry).
