A strong password is quite long (the closer it gets to 21 characters, the stronger it is). In addition, you should use a different password for each of your online services (email, bank account, social networks...).

More solutions to secure your digital banking

Discover our online security solutions to protect your business. From alerts and notifications to dual signature and the SecurID® token.

Use the alerts and notifications feature to stay up to date on all transactions and updates in the Internet and mobile banking solutions for businesses. You can customize them to fit your needs. Watch our demo to learn more.

Access rights management allows you to further protect yourself by defining multiple levels of access rights for each authorized user. You can determine each users’ role according to your operational needs for each user, ranging from a simple consultation to the initiation of a transaction or transaction authorization.

The access rights limit allows you to set a maximum number of transactions. This allows the user to initiate a transaction and approve it up to the maximum amount specified in their profile. If the amount exceeds the limit, the user will not be able to complete the transaction.

Watch our demo to learn how to easily activate this feature.

The dual signature feature allows you to validate certain actions with two signatures. You can activate it for your payments, government payments, e-Transfers or to manage your user rights and accesses. To use this feature, call us at 1-888-835-6281.

The SecurID ® access token is there to protect your account by restricting who has access to your finances.

You sign in to your account with a password and username that expires after 60 seconds.

To obtain a SecurID access token, you must complete the form found in your Internet banking solutions under Administrator options in the Users section.

Please note that if you’re signing in from an unregistered device, you will need to confirm your identity by answering one of your three pre-chosen identification questions.

It’s vital to choose a strong password to access your Internet and mobile banking solutions for businesses.

A strong password has at least 12 characters. Once a password hits 21 characters, it’s considered indecipherable from current technology. The more characters you add to your password, the more secure it becomes.

It’s important to remember that reusing the same password for all your account makes it easier for hackers to access your information. One of the ways they steal passwords is by buying stolen credentials and try them on a multitude of sites. So make sure you use only one password per application or website.

If you’re a victim of fraud, please call us at 1-888-835-6281, every day from 6 a.m. to midnight (ET).
