OTP via mobile message

​​​​​​​


NBG has deployed cutting-edge technology to enable its customers to perform cash- related transactions via its i-bank Internet, Phone, Mobile Βanking & i-bank Pay services enjoying greater convenience, security and freedom, by entering a one-time password (OTP) sent via Viber or SMS on the user’s mobile phone.
The OTP service is free of charge and is available to all users who use i-bank services:
• Individuals (Natural Persons) and
• Business Users (Legal entities / Businesses)

The Viber OTP is sent to the mobile phone number stated when registering for the service.


In the event that it’s not possible to send OTPs to your mobile phone via Viber (e.g. the app isn’t installed, or there’s no internet connection) or in case you don’t wish to receive OTPs via Viber (i.e. you’ve specifically chosen not to receive NBG messages through the app), you’ll receive your OTPs via SMS.

OTPs via Viber are just as secure as OTPs via SMS, as the Viber messages are fully encrypted from the time they are sent through to receipt by the user. In addition, you’ll get your OTPs even if you don’t have a good signal!

Individuals can activate the OTP service via Internet Banking in the section Security Settings> Manage OTP or by visiting a branch. Business customers can activate the service by visiting a branch. The OTP via mobile message service is available to Legal Entities for work.

Business users can activate the OTP service via mobile message by visiting a branch or via Internet Banking (if they have an administrator user with category S). The OTP service via mobile message is available to job positions with access to digital channels.


Each time you want to perform money and security transactions via i-bank Internet and Mobile banking, please follow the steps below:
• enter the transaction details
• click on "Continue", and then
• enter the OTP sent via message to your mobile device.

The OTP will be sent within a few seconds to the mobile phone number you have chosen when you registered to the OTP service via Viber.

Within a few seconds you'll receive on the mobile phone number you chose when registering to the service a Viber message sent by "i-bank" that will include:
• the main details of the transaction,
• a 6-digit code (OTP), and
• a 3-digit code (check code).

These three (3) sets of data are fully aligned with each other and correspond only to the specific transaction.
The OTP is valid for five (5) minutes, during which time you can enter in the relevant field:
• the 6-digit code received by mobile message, and then
• click on "Submit".

A 3-digit check code is displayed on your screen upon completion of the transaction. This 3-digit code should be the same as the 3-digit check code sent by mobile message.


If you perform your transaction via Phone Banking, please follow the instructions of our agent to enter the OTP.

In the event that it’s not possible to send OTPs to your mobile phone via Viber (e.g. the app isn’t installed, or there’s no internet connection) or in case you don’t wish to receive OTPs via Viber (i.e. you’ve specifically chosen not to receive NBG messages through the app), you’ll receive your OTPs via SMS.

If you don’t wish to receive OTPs via Viber, you can deactivate the option to receive OTPs via Viber by selecting the respective option in the message sent to you by NBG via Viber, and OTPs will continue to be sent via SMS.

You can reactivate Viber OTPs at any time through Viber by going to: More > Settings > Privacy > Block list > Unblock.

 

Each OTP (6-digit one-time password and 3-digit check code) can be used within five minutes. In the event that it is not entered within the five minutes, you have to ask for a new OTP in order to perform your transaction.

Each OTP is unique to a specific transaction, and cannot be used for another transaction. Ε.g. if you get  an OTP to pay a bill, this OTP cannot be used to transfer money to a third party's NBG account or to pay the same bill with different payment code or amount or another bill.

The OTP via mobile message service is "blocked" after four (4) failed attempts to enter an OTP. You should call our Contact Center (+30 210 4848484) in order to reset (unblock) the OTP service.

If you have activated the OTP via mobile message service and you have lost:
