## What is CA Auth ID?

NOTE: CA Auth ID is the new name of the former CA ArcotID PKI app.

The CA Auth ID App provides 2-factor strong authentication using your iPhone. Online sites using CA Auth ID authentication provide better logon security using something you’re already carrying, your iPhone. Using the CA Auth ID App is as simple as entering a password, and a lot more secure. 

How does it work?

To access your favorite site or network, you first get a CA Auth ID soft token from that site. Your CA Auth ID soft token is unique to you and to the site you are accessing. When you enter your password, the CA Auth ID app combines your password with the CA Auth ID soft token on the iPhone to generate a identification certificate and sends it automatically to the site for verification. Your password is not stored on the phone, nor is it transmitted to the web portal.

A fraudster cannot access your accounts with just your password or just your iPhone. Even if you lose your iPhone, the attacker cannot brute-forece attack the password. The CA Auth ID soft token can be used to securely access your online banking accounts, personal Web sites, corporate VPNs or anywhere that you typically use a password. 

Why is it secure?

Each user account gets a CA Auth ID soft token. The CA Auth ID soft token contains PKI-based cryptographic keys used to securely authenticate you to an online site. CA Technology’s patented technology protects these keys so that an attacker cannot use them, even if he gets your iPhone. 

How can I use it?

Follow the instructions on the site that issued the CA Auth ID soft token.

Or if you want to sign up for a demonstration account and experience CA Auth ID authentication for yourself, go to http://mobile.arcot.com/aid/gettingstarted.html

### 1/5 — Update please

*2017-10-02*

Any ETA on an update for iOS 11?  Just crashes after entering password now. Thanks!!

### 1/5 — Ugh.

*2015-10-15*

An old app which has properly worked for me only once. Basically worthless.

### 1/5 — Pathetic Piece of Programming

*2014-09-03*

It's a shame that a company in the scope of CA cannot afford to write a working User Interface. 

I mean, hey! If the UI is that badly written with only a couple of simple screens - how good is the actual VPN it is supposed to create?

I'd be ashamed to let such a piece of programming out into the open. 

I hope, that there a patch coming up to make the program usable.

### 1/5 — Terrible

*2014-07-24*

Seems like CA don’t feel the need for a real mobile app, it does not rotate on an iPad, meaning that using it to login to any remote apps is annoying. it doesn’t scale on the screen appropriately. Needs a redesign and and update

### 1/5 — Does not redirect to website after entering credentials

*2014-02-07*

When going to a website that uses ArcotID authentication, I'm redirected to the ArcotID App for my credentials.  After I enter my credentials, the App closes (minimizes) but never redirects back to the browser to allow entrance.  I've tried turning the iPad (2nd generation) off and back on, deleting and reinstalling the App and get the same result.  Fix it and I'll rate it 5 stars.

### 5/5 — Works great.

*2012-07-26*

You need to go to the gettingstarted page to create a test account.

### 1/5 — Worst. User. Experience. Ever.

*2012-06-05*

I just followed vague instructions to a demo page for about the 5th time and came to a dead end every time with NO FURTHER INSTRUCTIONS! Never mind the misspellings that make me wonder if this is even a legitimate app or company in the first place.

### 1/5 — Worst app.

*2012-04-15*

Using this for mls listings site access. Everybody is bashing the developer (which in my view they have the right and should) but my gripe is with so many complaints why aren't the real estate sites adopting a different standard. The sites that charge us so much every year need to stop being morons with technology and show us they can actually solve a tech issue. Especially as more and more of us are using tablets and phones towards our production. It's not like using technology is going to go away on the contrary it's only going to be more present in the market. I'd give this company and mls sites negative stars but it won't allow me.

### 1/5 — Garbage

*2012-03-04*

- million stars by far the worst app on the market.

### 1/5 — Total Joke

*2011-08-12*

Terrible setup.  Skips steps. Directions are wrong.  Worst software I have ever used.
