Most teams share credentials insecurely — Slack DMs, email, shared spreadsheets. Here's what's wrong with each method, and how to do it properly with encryption, access control and an audit trail.
Messages are stored on the platform's servers, searchable by workspace admins, accessible to the platform itself, and sit in message history indefinitely. Credentials in Slack DMs have been exposed in multiple breach investigations.
Email is stored unencrypted on mail servers, passes through multiple servers in transit, gets forwarded accidentally and sits in inboxes for years. A single compromised email account exposes everything shared that way.
Everyone with access sees everything. No audit trail of who accessed what item. No field-level encryption. Offboarding requires changing every password the person could have seen.
Readable by everyone with workspace access. Link sharing can accidentally expose the page. No encryption. No audit trail. Often indexed in workspace search.
One compromised master password exposes everything. No individual accountability — all actions appear under one account. No per-item access control.
Credentials should be encrypted before they leave your device and before they are stored anywhere. This means even if the platform is breached, attackers see only ciphertext.
Every team member should have their own account with their own master password. This enables individual accountability — you know who accessed what — and limits blast radius if one account is compromised.
Not everyone should have access to everything. Share credentials with the people who need them, in vaults scoped to that project or client. Contractors should have access to less than permanent employees.
Every access, copy and edit should be logged with a timestamp, user identity and IP. If a credential is used without authorisation, you can identify who accessed it and when.
When someone leaves — permanently or at the end of a contract — their access should be revocable with a single action. You should then be able to identify which credentials they had access to so you can rotate them.
Create a vault scoped to the project, client or team who needs the credentials. Name it clearly — 'Acme Corp Production', 'Marketing Tools', 'AWS Infrastructure'.
Add logins, API keys, SSH keys or secure notes to the vault. Each secret is encrypted in your browser before it leaves your device — the server never sees plaintext.
Add team members to the vault as Admin, Member (read/write) or Read-only. Each person has their own account — no shared master password.
Instead of sharing credentials ad hoc, everyone copies from the vault. The copy action is logged. If a credential needs to change, update it once and everyone sees the new value.
When someone leaves, remove them in Settings → Members. SealedKeys shows you every credential they had access to via the offboarding checklist — rotate those credentials, done.
The safest way is via a zero-knowledge encrypted team vault where both parties have their own accounts. Each person logs in individually, sees only what they're authorised for, and every access is logged. SealedKeys, Bitwarden and 1Password all support this model. Avoid sharing credentials via email, Slack or any unencrypted channel.
No. Slack messages are stored on Slack's servers and are searchable by workspace admins. They sit in message history indefinitely. If a Slack account or the Slack platform is compromised, credentials shared via DM are exposed. Credentials in Slack messages have appeared in multiple breach investigations.
With a zero-knowledge vault like SealedKeys, you can grant someone Read-only access to a specific vault. They can copy the credential and use it without necessarily seeing the plaintext in a UI that makes it easy to record. However, true 'blind' credential sharing — where the recipient can use a credential without ever seeing it — requires purpose-built PAM tooling, not a password manager.
Immediately rotate the credential at the source (the service it authenticates to). Update the value in SealedKeys so team members have the new credential. Check the audit log to identify which team members accessed it and when — this helps you understand how the compromise might have occurred. Review the access list and remove any team members who no longer need it.
Create a vault scoped to what the contractor needs — don't add them to your main team vault. Give them Read-only access. When the engagement ends, remove them from SealedKeys. The offboarding checklist shows everything they accessed — rotate those credentials. Never share your main team vault or give contractors Admin access.
In SealedKeys, every view, copy, edit and deletion of a secret is logged with timestamp, user email and IP address. Go to Audit Log, filter by secret name or vault, and you have a full access history. This is essential for incident response and compliance.
SealedKeys gives your team encrypted vaults, individual accounts and a full audit trail. 25 items free, no credit card.
