TL;DR: The NSA’s updated Cisco password guidance, highlighted in Bitwarden’s 2025 password security report, reinforces that Type 8 hashing is the recommended storage scheme and that weak device credential practices can expose plaintext-equivalent access data, especially in infrastructure targeted by persistent adversaries. The practical issue is not password complexity alone, but whether network device credentials are stored and governed in a way that resists compromise.
NHIMG editorial — based on content published by Bitwarden: an analysis of NSA guidance on Cisco password types and credential protection
By the numbers:
- Type 8 passwords are hashed with PBKDF2, SHA-256, an 80-bit salt, and 20,000 iterations.
- The 2025 Bitwarden State of Password Security report gave the NSA a Very Good rating for its password guidance.
Questions worth separating out
Q: How should teams handle weak Cisco password types on network devices?
A: Teams should inventory password schemes, replace weak formats with the strongest supported option, and prioritise devices that expose management access or support critical infrastructure.
Q: Why do network device credentials need NHI governance?
A: Because routers, switches, and similar infrastructure accounts act as non-human identities that can persist, confer privilege, and enable lateral reach.
Q: What breaks when Cisco credentials are stored in weak password formats?
A: Weak formats lower the attacker cost of recovering plaintext credentials from configuration material or backups.
Practitioner guidance
- Audit Cisco password types across network devices Identify where Type 4, Type 5, Type 7, or other weaker schemes remain in use, then map each device owner and remediation path.
- Bring network device accounts into NHI lifecycle review Assign ownership, review cadence, and offboarding responsibility for every router and switch credential.
- Move secrets out of configuration files where possible Reduce reliance on stored credentials by using centrally governed secrets management and by removing reusable secrets from ad hoc device configs.

Type 8 is the practical baseline because weak Cisco password storage turns device credentials into reusable identity material. The NSA’s guidance reflects a basic NHI truth: once a password can be recovered or cracked, the device is no longer protected by policy, only by attacker effort. For network teams, the question is not whether passwords exist, but whether the storage scheme meaningfully raises the cost of compromise. Practitioners should treat password type as a first-class control variable.
A few things that frame the scale:
- 23.7% of organisations share secrets through insecure methods such as email or messaging applications, according to The 2024 Non-Human Identity Security Report.
- Only 19.6% of security professionals express strong confidence in their organisation's ability to securely manage non-human workload identities, according to The 2024 Non-Human Identity Security Report.
A question worth separating out:
Q: How do you know if device password governance is actually working?
A: You should be able to show complete inventory, ownership, and rotation status for infrastructure credentials, plus evidence that weak password types have been eliminated. If teams cannot answer who owns a device secret, where it is stored, and when it was last reviewed, governance is not working.
