Sharing passwords is often necessary, but doing it wrong can lead to serious security breaches. In this guide, we cover the only safe way to share credentials.
The problem with how we usually share passwords
When you send a password over email, Slack, or Microsoft Teams, that password is saved in the chat history forever. If anyone ever hacks that email inbox or slack account, they gain access to all those passwords.
Even worse, chat logs are often backed up to the cloud without end-to-end encryption, exposing your credentials to third-party servers.
Best practices for sharing passwords
1. Never send passwords in plain text
Always use a secure medium to transmit the actual characters of the password.
2. Use burn-after-reading links
A self-destructing link ensures the password can only be viewed once. If a hacker intercepts the link later, it will already be destroyed.
3. Separate the username and password
Send the username via Slack, and send the PassLink with the password via email. This split-knowledge approach adds a layer of defense.

Meeting SOC2 and ISO27001 Compliance
For businesses, using an encrypted, zero-knowledge sharing tool like PassLink helps satisfy compliance requirements for secure data transmission and credential management.
Real-world password sharing scenarios
IT sharing admin credentials with a new hire
Use a one-time link with a 1-hour expiration. Once the new hire views and saves the password, the link self-destructs. No evidence remains in email or chat.
Agency sharing social media logins with a client
Create a password-protected link. Email the link to the client, then text or call them with the link password. This two-channel approach prevents unauthorized access.
Freelancer receiving database access from a startup
Ask the startup to send credentials via PassLink instead of Slack. After saving the credentials locally, rotate them when the project ends.
Password managers vs one-time links
Password managers like 1Password and Bitwarden are excellent for storing and auto-filling your own passwords. However, they are not ideal for sharing credentials with people outside your organization.
One-time links complement password managers perfectly. Use the manager for storage and the link for secure one-time transmission to external parties.
Frequently asked questions
What is the safest way to share a password?
The safest method is an encrypted, self-destructing link like PassLink. The password is encrypted on your device, transmitted via a one-time URL, and permanently deleted after viewing.

Yes. PassLink is completely free, requires no account, and provides bank-grade AES encryption with zero-knowledge architecture.
Should I change a password after sharing it?
Yes, it is best practice to rotate shared credentials after the recipient has saved them, especially if the password was shared with a temporary collaborator.
Conclusion
Sharing passwords securely is not optional in 2026. With data breaches costing millions and credential stuffing attacks on the rise, using encrypted, ephemeral links is the minimum standard for any professional. PassLink makes it free, fast, and zero-knowledge.
