In today's world where information security is increasingly important, controlling document access times has become a vital means of protecting sensitive information. By limiting access times, you can effectively prevent documents from being over-distributed or maliciously abused.

Inform users in advance: Recommend informing users about access count limits when sharing to avoid misunderstandings
Backup important documents: Keep original backups of important documents as a precaution
Regular setting reviews: Periodically check access records and adjust limit strategies as needed
Consider user experience: Find reasonable balance between security and user experience

Frequently Asked Questions

Q: Can I reset access counts after they're used up?

A: Yes. In the admin dashboard, you can reset access counts for documents that have reached their limit, or remove count restrictions entirely. Changes take effect immediately.

Q: Do multiple accesses by the same user count separately?

A: By default, each document opening counts as one access. However, you can configure IP or device-based deduplication so that the same IP or device only counts once within a certain timeframe.

Q: How can I check remaining access counts?

A: Administrators can view remaining access counts in real-time through the dashboard. For viewers, we can optionally display remaining counts on the document page.

Q: Do access limits affect search engine indexing?

A: Documents with access limits will not be indexed by search engines, which is also a way to protect document privacy. If you need SEO-friendly sharing, please use other sharing methods.

Q: Can I set different access counts for different people?

A: Yes. By creating different sharing links, you can set different access count limits for different user groups. For example, VIP users get 10 accesses, regular users get 3.

Q: Can access count limits be combined with other security measures?

A: Absolutely. Access count limits can be combined with password protection, expiration control, IP restrictions, email verification, and other security measures to form multi-layer protection.

Q: Can I immediately revoke all access permissions if security issues are discovered?

A: Yes. The admin dashboard has an emergency revocation feature that can immediately invalidate all sharing links and stop any further access. This is an important component of our security system.
