Our app is a security tool that enhances account protection by generating time-based, one-time passwords (TOTPs) for two-factor authentication (2FA). It provides an additional layer of security beyond traditional passwords by requiring users to enter a unique code generated by the app when logging into their accounts. The app works offline, and codes typically refresh every 30 seconds, making them harder for hackers to intercept or predict. It supports multiple accounts and is commonly used for securing emails, social media, banking, and more. After purchasing an auto-renewable subscription, you will gain access to all features, such as: - Unlimited Code Generation: Create and manage an unlimited number of one-time authentication codes for all linked accounts. - Multi-device Sync: Sync authentication codes across multiple devices for easier access. - Cloud Backup: Securely back up 2FA data to the cloud, ensuring easy recovery in case of device loss. Subscription Details: - Payment is processed through your iTunes Account upon purchase confirmation. - Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. - Your account will be charged for renewal within 24 hours before the end of the current period, with the renewal cost clearly indicated. - Users can manage their subscriptions and turn off auto-renewal in Account Settings after purchase. - Any unused portion of a free trial period, if offered, will be forfeited upon subscription purchase, where applicable.
