ワンタイム

ワンタイム is a one-time password-generation app for Japan. These disposable passwords can be used for online shopping and ensure no identity theft.

Verify compatible services

To use ワンタイム, you need a compatible bank card, so you must check with your bank if your card is compatible. You will also need an email address for the initial setup and to add each service you want to use. After registering, you have to add the services for which you want to use one-time passwords individually.

Single-use codes expire after a few seconds

Each password expires after a few seconds, so you must enter it quickly. The time left to enter the password is displayed just below the generated number, and you can hit the "copy" button to paste it more quickly into the login page of the service you want to access.

Check each token's expiration date

Each service registered on ワンタイム has a token. Each token has a specific expiration date, which varies depending on the service. You can delete the tokens you no longer need, but first, make sure you do not need to log in to your account because once you delete them, you will have to reset your account.
