오티서랍 OTP - 2단계 인증기

Organize 2-step verification codes for multiple accounts in the OT Drawer.

Generate verification codes on your device without signing up, and manage personal and work accounts separately.

**Verification Codes in One Place**

Supports standard TOTP and HOTP accounts. Register by scanning the standard OTP QR code provided by the service or by manually entering the authentication key. Verification code generation is handled on the device without an internet connection.

**Easy-to-Find Account Organization**

Classify accounts into two levels of categories: top and bottom. You can keep marked as important and pin favorites to the top of the list. Search within the device by display name, service name, account name, or category path. Deleting a category moves the account without deleting it. When deleting an account, you must verify the target and undergo device authentication. Deleting an account from the app does not disable 2-step verification for the corresponding service.

**Encrypted Storage and Backup**

Authentication information is encrypted and stored on the device. Create an encrypted backup file with a separate password and select the storage location yourself. You can select a backup file to restore, or check the included items first using a restore check that does not alter the existing account.

** Personalized Device Lock

You can set Lock at Startup and Lock in Use separately. Both options are set to Off by default, and encryption of credentials is maintained even when the lock is turned off. Device authentication is required for account deletion, backup/restore, and changing lock settings.

Easy-to-Recognize Names and Icons

You can change the display names and icons for each account. Site icons are retrieved by connecting to the corresponding site and icon server only when you enter an address and press the Import button. The imported icons are stored on the device, and authentication keys and account names are not sent in icon requests.

Please Check Before Use

OT Drawer is an authenticator used in conjunction with the 2-step verification settings of each service. Please set up 2-step verification on the service first. If the time-based verification code is incorrect, please check the date and time on your device.

Prepare an encrypted backup before deleting the app or losing your device. It is recommended to store backup files and passwords in separate, secure locations. Backup passwords cannot be recovered from the app, and data may not be recoverable without a backup. Cloud storage by selected external file providers follows the provider's settings.
