How to Share Passwords Securely in 2026

We all need to share passwords sometimes. Maybe you're giving a contractor access to a shared account, helping a family member log in to a streaming service, or onboarding a new team member. The question isn't whether you'll share a password — it's how you'll do it safely.

Most people default to the easiest method: copying the password into a chat message, email, or text. That's a problem — and a big one.

Why Sharing Passwords in Plain Text Is Dangerous

When you send a password through email, Slack, or SMS, it gets stored in multiple places: your sent folder, the recipient's inbox, server logs, backup systems, and potentially on every device synced to those accounts. A single breach of any of those systems exposes your password.

Even "private" messages on platforms like Slack or Microsoft Teams are accessible to workspace administrators and are stored indefinitely unless explicitly deleted. The password you sent six months ago? It's still sitting in a searchable message history.

The Safest Methods to Share Passwords

1. Self-Destructing Secret Links

The simplest secure method is a one-time secret link. You paste your password into a tool like Authly Send, which encrypts it in your browser and gives you a unique link. The recipient opens the link, sees the password, and the link permanently self-destructs. No message history, no server storage, no trail.

This works perfectly for sharing passwords with people who aren't on your password manager — clients, family members, freelancers, or anyone you need to give temporary access.

2. Password Managers with Sharing Features

If you and the recipient both use the same password manager (1Password, Bitwarden, Dashlane), most offer built-in sharing. This is great for teams that are already on the same platform, but it doesn't help when you need to share with someone outside your organization.

3. In-Person or Phone Call

For truly critical credentials (root server passwords, master keys), verbal communication over a phone call or in person is the most secure option. Nothing is stored digitally. Of course, this doesn't scale.

What to Avoid

• Email — Stored permanently on multiple servers, often unencrypted in transit
• SMS / text messages — Vulnerable to SIM swapping, stored by carriers
• Slack / Teams DMs — Searchable, logged, accessible to admins
• Sticky notes or shared documents — Easily discovered, no access control
• Splitting passwords across messages — False sense of security; if one channel is compromised, the other usually is too

Best Practices When Sharing Passwords

1. Use a tool with encryption — Make sure the password is encrypted before it leaves your device
2. Set an expiration — Don't let shared passwords live forever. Use a tool that auto-deletes after a set time or after one view
3. Add PIN protection — For extra security, protect the shared secret with a PIN that you communicate through a separate channel
4. Change passwords after sharing — If you shared a credential for temporary access, rotate it once the task is done
5. Use unique passwords — Never share a password that's reused across accounts. If you must share access, make sure it's to an account with a unique, strong password

How Authly Send Makes Password Sharing Safe

Authly Send was built specifically for this use case. It uses AES-256 encryption in your browser — the password is encrypted before it ever leaves your device. The decryption key is embedded in the URL fragment (the part after #), which is never sent to our servers.

After the recipient views the password, it's permanently deleted. You can also add a PIN for two-factor protection and choose an expiration time of 1 hour, 24 hours, or 7 days. No account required — just paste, encrypt, and share.
