2-Step with Email

This is the default 2-Step verification method available on all Calxa accounts. When signing in on a device that has not been previously trusted, Calxa will send a verification code to the email address used to sign in. The code sent to your email is valid for 15 mins. A  code entered after 15 mins will return an error that the incorrect code was entered.  

2-Step with SMS

You can optionally add a phone number for 2-Step verification via SMS.

How it works

When you use this option Calxa adds a record to your browsers storage that identifies your device on the current network. This record stores the following details. 

  • Public IP Address
    • If you move locations with the same device like from between home and office for example then these 2 locations will require separate validation. 
    • If you visit a new location that you've not validated before like a clients office, this will require separate validation.
    • If your internet service provider (ISP) changes your public IP address you will be required to validate the new IP address. This can happen if you restart your router for example. 
  • User Agent (browser)
    • Signing in from a different browser on the same machine will require separate validation.
    • Signing in from a different machine will require separate validation.   
  • Timestamp 
    • Once the timestamp is greater then 30 days old, a new validation will be required. 

Check that all of the above remains the same each time you sign in before progressing to the next troubleshooting steps.
