Difference between revisions of "Trigger: Failed Login Attempt"

Latest revision as of 22:56, 5 January 2026

This trigger will fire whenever an incorrect passcode (not fingerprint) is entered on the lock screen. Note that this trigger will only fire when a legal login attempt is made (for example a 3 digit PIN is not allowed so will not cause this trigger to fire).

Options

Number of Failures - Select how many failed login attempts should occur before the trigger fires (1-10).

Time Period - When the failure count is greater than 1, specify the time period within which the failures must occur:
- 1 minute
- 2 minutes
- 5 minutes
- 10 minutes
- 30 minutes
- 1 hour

Examples

Example 1: Take photo after any failed login

Triggers

Failed Login Attempt [Any failed login]

Actions

Take Photo: Front Camera
Save to: /sdcard/MacroDroid/FailedLogins/

Example 2: Send alert after multiple failed attempts

Triggers

Failed Login Attempt [3 failures in 5 minutes]

Actions

Take Photo: Front Camera
Send SMS: To owner, "Multiple failed login attempts detected on your device"
Share last photo: (To email address of your choice)

Example 3: Lock device after repeated failures

Triggers

Failed Login Attempt [5 failures in 10 minutes]

Actions

Play Sound: Alarm
Notification: Security Alert - Device may be compromised

Notes

This trigger requires Device Administrator permissions to function. MacroDroid must be enabled as a Device Administrator in your device settings.
Once Device Administrator is enabled, MacroDroid cannot be uninstalled through normal methods. To uninstall:
- Disable Device Administrator in Settings > Security > Device Administrators
- Or use the uninstall option in MacroDroid's drawer menu
This trigger only responds to incorrect passcode entries, NOT fingerprint authentication failures.
The trigger specifically responds to "legal" login attempts - incomplete entries (like a 3-digit PIN when 4 digits are required) will not trigger.
Time periods available: 60 seconds (1 min), 120 seconds (2 min), 300 seconds (5 min), 600 seconds (10 min), 1800 seconds (30 min), 3600 seconds (1 hour).
