# Login proccess
When trying to connect to a web application protected by *SecureAccess® CLOUD* (e.g. an intranet portal), the following access window will be shown:
Type your username and press the *Enter key* or click in *Next* button.
Then type your password. If the two-factor authentication is enabled for your account, an extra window will be displayed to link your *SecureAccess® CLOUD* account to your mobile device.
The displayed window depends of the option set by your organization's administrator. There are two types, ***SecureAccess® PUSH,*** ***SecureAccess® TOTP*** and ***Fido U2F.***
### Link your mobile device with ***SecureAccess***® PUSH
If the *SecureAccess® PUSH* has been set as two factor authentication for your account, a new window to link your mobile device will be displayed just after the access window.
Open the *SecureAccess® 2FA* app in your device and scan the QR code displayed by *SecureAccess® CLOUD*, as shown in the following image:
Once the *QR code* has been scanned, the *SecureAccess® CLOUD* account will be linked to your mobile device thought the *SecureAccess® 2FA*. Now click in the *Finish* button.
A notification will be sent to your mobile device to grant access to once the *QR code* has been scanned, the *SecureAccess® CLOUD* account will be linked to your mobile device thought the *SecureAccess® 2FA*.
Since this moment, any new access to a web application through *SecureAccess® CLOUD*, will send a notification to the linked device asking for confirmation. In this way, even if someone knows your credentials, the access to web applications protected by *SecureAccess® CLOUD* will be blocked as he does not have access to your mobile device.
### Link your device with SecureAccess® TOTP
If your user account has been configured to use two factor authentication based in *SecureAccess® TOTP*, a new window similar to the image below will be displayed in the first access to your account.
As first step, open the app in your mobile device and scan the *QR code*.
Once the code has been scanned, your *SecureAccess® CLOUD* account will be linked to your mobile device. The *two-factor authentication code TOTP* for your account will be displayed in the app.
Type the given code in the ***TOTP Code*** field located just below the *QR code* and click the *Finish* button.
At this point your session will be authenticated in *SecureAccess® CLOUD* and the access to web applications of your organization will be granted.
Since this moment, as your mobile device is linked to your *SecureAccess® CLOUD* account, *SecureAccess® CLOUD* will ask for a *TOTP* code before given access to the web applications. A new TOTP code is generated each minute, in this way, even if someone knows your credentials, the access to web applications protected by *SecureAccess® CLOUD* will be blocked as he does not have access to your mobile device.
**Note:** Date and time must be properly set in your mobile device for ensuring the right behavior of *SecureAccess® TOTP.*
## **Link your Fido U2F**
If your user account has been configured to use an Fido U2F usb device, when you have inserted your credentials the system will solicites you to plug in your device.
Click *Next* and your browser will solicite you that confirm clicking your Fido U2F device.
Click your *Fido U2F* confirm button, now your device will be linked correctly.
