Start Guide

User account

After a customer Company registration on the Cloud platform, a message containing administrator password is sent to the Company’s email. Administrator login has the following format: admin@<customer>, where customer is the ID of the Company, specified during the registration


For security reasons, we strongly recommend to use the administrator account for working in the IAM section only. For operating with other cloud services, we recommend you to use only additional accounts, created without administrator rights.

Authorization in CROC Cloud


Password usage recommendations:
  • The password used shall be longer than 7 characters and contain letters, digits and special characters.

  • The new password should differ significantly from at least 4 previously used passwords.

  • It is recommended to change the password at least once every 90 days.

  • Do not store the password in plain text.

When you first log into CROC Cloud, enter the username and password. After a successful login, CROC Cloud will ask you to change a password.

To protect your profile, set a strong password yourself or generate it by clicking Generate password. Follow the on-screen instructions, click Change Password. Use new password to operate with CROC Cloud.

Configuring account, notifications and API access

Changing your personal data and notification settings

You can change your personal data in the profile settings. Modify corresponding fields to change the name, email address, and phone number.

Two-factor authentication

Use two-factor authentication to provide additional security for your account. You need to have an access to a tablet or smartphone with a two-factor authentication app installed.

Click Set up 2FA to enable two-factor authentication. Then open two-factor authentication app installed on your smartphone or tablet (e.g. Google Authenticator) and add your account by scanning QR code


The device with the app installed must use the time and time zone of the network.

From this moment, at each logging in to CROC Cloud you will have to enter one-time passwords generated by two-factor authentication app on your device.

To return to single-factor authentication, click Disable 2FA and confirm the action.
