Secure Transfer Password with 4net | Self-Destruct Link
In daily operations, whether it’s internal collaboration or external communication with clients, securely transmitting account credentials remains a vital part of IT practices. Sinokap has repeatedly stressed a fundamental rule: Never send both the account and password through the same transmission channel. Although the principle appears straightforward, it is frequently overlooked in real-world scenarios.
Today, we’d like to introduce a secure password sharing tool that requires no software installation and can be used directly via a web browser. Developed and operated by Swiss IT solution provider 4net, the tool complies with international privacy regulations such as GDPR. It enables the safe transmission of sensitive information through self-destructing temporary links.
Key Features of 4net
1. Multi-layered security
End-to-end encryption protects sensitive data from interception or unauthorized access. Additionally, encryption, auto-destruction, and expiration features work in parallel to significantly reduce the risk of data leakage.
2. Password generator
Instantly create strong, complex passwords to enhance your overall credential security.
3. Access limit control
You can specify how many times a link can be viewed, effectively preventing repeated malicious access.
4. Expiration timer
Set a validity period for each link in advance to ensure that passwords are only accessible during the intended time frame.
5. Multi-language support
Links can be displayed in different languages based on recipient preferences, making secure communication easier across global teams.
6. Self-destruction feature
Once the set number of views or time limit is reached, the system automatically deletes the link—preventing prolonged exposure of sensitive credentials.
Step-by-Step Instructions
1. Visit the Website
Go to https://password.4net.ch/ in your browser.
2. Enter a Password
Enter a strong password, or simply click the "Generate Password" button.
3. Set Link Parameters
- Days：Define how long the link will remain valid.
- Views：Limit the maximum number of times the link can be accessed.
- Check the boxes for “use a 1-click retrieval step” and “Allow immediate deletion.”
- Activate passphrase lockdown and enter a separate password to access the link.
4. Generate the Link
Click the “Push It!” button to generate a unique sharing link. This link will self-destruct once the time or view limit is reached.
5. Share the Link
Select a preferred language for the recipient, then copy and send the generated link.
Sinokap recommends sending the generated link through an encrypted communication channel—such as secure email or an encrypted messaging app—for maximum safety.
