The duration of a security lockout on an iPhone can vary depending on the specific circumstances and settings configured by the user. Here are the possible scenarios and their corresponding durations:
1. Incorrect passcode attempts: When an incorrect passcode is entered multiple times, the iPhone enforces a lockout period to prevent unauthorized access. The lockout durations typically increase with each successive incorrect attempt. As of iOS 16, the lockout periods are as follows:
- 1-9 incorrect attempts: No lockout, but a time delay is introduced between attempts.
- 10 incorrect attempts: 1-minute lockout.
- 11 incorrect attempts: 5-minute lockout.
- 12-15 incorrect attempts: 15-minute lockout.
- 16-19 incorrect attempts: 1-hour lockout.
- 20 incorrect attempts: The device is disabled, and a connection to iTunes or Finder is required to regain access.
2. Remote device management lockout: If an iPhone is enrolled in a mobile device management (MDM) system, the lockout behavior can be controlled remotely by an administrator. The lockout duration can be customized to align with the organization's security policies. The user should contact their IT department or MDM administrator for specific details.
It's important to note that the lockout durations mentioned above could be subject to change in future iOS updates. Users should refer to official Apple documentation or support channels for the most up-to-date information on lockout durations.
