Why Use a Self-Destructing Temporary Link?
When sharing temporary credentials, server logs, or one-time configuration notes, the greatest security risk is longevity: permanent links stay indexed, stored in message history, and vulnerable to future leaks.
A temporary paste link solves this by attaching an explicit time-to-live (TTL) to the data. When the timer expires, the payload is permanently purged from active memory.
1:1 Silent Collision Retry Architecture
Fastcopy assigns a short, 4-digit code (from 0000 to 9999) to each temporary paste. To prevent code collisions:
- Cryptographic Random Allocation: Codes are generated using secure random selection.
- Backend Collision Detection: If an allocated 4-digit code is currently in use, Fastcopy silently re-rolls another number without interrupting the user.
- Code Recycling: The moment a paste expires and purges, that 4-digit code returns to the available pool for future users.
Expiration Windows
- 10 Minutes: Ideal for one-time passwords, 2FA tokens, and sensitive keys.
- 1 Hour: Perfect for live meeting notes and temporary conference documents.
- 24 Hours (Guest Default): Convenient for daily coding snippets, terminal outputs, and cross-device links.
