Payment FAQ
Contains a summary of FAQs regarding the payment function of the YubiOn FIDO2 Server Service.
1. About Pricing Plans and License Structure
I don’t know the number of licenses required for implementation. What is MAU?
This service is contracted on an MAU (Monthly Active User) basis. Please check here for details.
What happens if the MAU exceeds the limit (10 users) on the free plan?
Since the free plan does not have a mechanism for excess charges, authentication by API will stop immediately when the number of users exceeds 10. If you wish to continue using the service, please consider upgrading to a paid license.
2. About Payment and Billing
What types of credit cards can be settled?
Please check Payment Methods and Billing Mechanism for available credit cards.
When is the timing of billing for fees?
When purchasing a paid license for the first time, it will be settled immediately. Continuous settlement is performed on the 1st of every month.
Please check Payment Methods and Billing Mechanism for details.
Can I make direct transactions (invoice payment, etc.)?
If you wish to pay by methods other than credit card, please contact us.
3. About Plan Changes and MAU Excess
Is it possible to change the license plan later?
Yes, it is possible. Updates to a higher plan will be reflected immediately after settling the difference, but updates to a lower plan will be applied from the next month.
Please check here for details.
What happens to the fee if the MAU (Monthly Active User) exceeds the limit?
If the MAU limit of your contract plan is exceeded, “excess charges” will be incurred according to the number of excess users.
Excess charges will be billed separately from the monthly basic fee of the next month. Please check here for excess charges.
Are there any notifications if the MAU is likely to exceed the limit?
Yes. There is an “MAU Excess Warning” function that notifies the person in charge by email when a preset threshold is exceeded. Please check Change MAU Excess Warning Settings for the setting method.
4. About Trouble and Contract Changes
The payment failed. What should I do?
Please check the expiration date and limit of the registered credit card.
Please check here for how to change the currently registered card information.
The payment administrator is resigning. How can I change the payment administrator?
Please set a new payment administrator from “Change” in the payment administrator section of the billing dashboard screen. Only one payment administrator can be set at any time. Please check Set/Change Payment Administrator for details.
Will a refund be made if I cancel the license midway?
We do not support refunds (prorated settlement, etc.) of fees once paid. When the cancellation procedure is performed, it will immediately transition to a free license, and API authentication may stop. Please check here for details.
