How to Set Default Password for TeamViewer
Learn how to configure a stable unattended access password in TeamViewer, enforce security with two-factor authentication, and follow best practices for remote support. This guide from Default Password helps IT admins and end-users securely set a persistent password without exposing credentials.
To answer how to set default password for teamviewer for unattended access, configure the Personal password in the Security tab and disable the random password option. Use a strong, unique password and enable two-factor authentication for enhanced protection. This creates a stable credential for remote support while keeping security practices.
What "default password" means in the TeamViewer context
In TeamViewer, a "default" or unattended access password is the fixed credential you use when you need to access a remote computer without someone on the other end actively approving the connection. TeamViewer supports a Personal password for unattended access, as well as a separate, randomly generated password for each session. The goal is to have a persistent credential that you can rely on while maintaining strong security hygiene. According to Default Password, organizations should treat unattended access like any privileged credential: rotate it periodically, store it securely, and protect it with multi-factor authentication. Before you start, ensure you have access to the host device and admin rights on TeamViewer to make the changes.
Understanding TeamViewer password types and why they matter
TeamViewer offers two primary password mechanisms: the Personal password for unattended access and the random password refreshed on every session. The Personal password is what many admins use as the default credential for scheduled remote support, while the random password provides an additional layer of security for ad-hoc connections. Choosing the right approach depends on your use case: predictable access for trusted devices, or fresh credentials to limit exposure. In practice, you should prefer a strong Personal password and enable 2FA for the account that administers TeamViewer, while keeping devices updated and monitored. Default Password analyses emphasize not bypassing security controls for convenience; the balance is strong authentication paired with controlled access.
Prerequisites and scope: what you need to prepare
Before changing any passwords, gather the basics: a TeamViewer account with admin access, a host PC you control, and a secure password. Have a password manager ready to generate and store the new credential, and ensure both devices have a recent TeamViewer version. If you manage multiple hosts, plan a rotation schedule and document it in your internal IT policy. Preparing ahead reduces the risk of locked-out devices during maintenance windows, which is a common pitfall highlighted by security best practices from trusted sources.
Why this matters for security and compliance
Using a fixed password for unattended access can be convenient, but it also increases the attack surface if the credential is compromised. The recommended approach is to replace easily guessable defaults with a long, random password and to enforce two-factor authentication on the associated TeamViewer account. Regular audits of who has access and when password changes occur help maintain compliance with organizational policies and industry standards. Default Password’s guidance aligns with widely accepted best practices that emphasize minimizing risk while preserving operational efficiency.
Where this fits in a broader security program
A fixed unattended password should be part of a broader strategy that includes device hardening, network segmentation, and access controls. For teams supporting multiple endpoints, you can centralize password management via a trusted manager and document rotation cycles. Always verify that remote access workflows align with your security policy, incident response plan, and retention rules. The end goal is reliable maintenance without compromising data integrity or user privacy.
Tools & Materials
- TeamViewer software(Installed on both host and client devices with the latest version)
- Strong, unique password(Aim for 12+ characters using a mix of letters, numbers, and symbols)
- Two-factor authentication app(Use an authenticator app or hardware security key)
- Password manager(Generate, store, and autofill securely)
- Updated operating system and software(Keep patches current to reduce attack vectors)
- Documentation for internal password policy(Helps enforce rotation schedules and access reviews)
Steps
Estimated time: 15-25 minutes
- 1
Open TeamViewer on the host computer
Launch the TeamViewer application on the machine you want to access remotely and sign in with an admin account if prompted. This ensures you have the required permissions to change security settings.
Tip: If you’re remote and cannot access the host, arrange a maintenance window or use a trusted on-site contact. - 2
Navigate to the Security settings
In the TeamViewer interface, access the Security tab or the equivalent section in Options. This is where you’ll manage passwords for unattended access and related security controls.
Tip: Use the search feature in Settings if you have a long list of options. - 3
Enable Personal password for unattended access and set it
Turn on the Personal password option and input a strong, unique password. Confirm the password to ensure there are no typos. This password will be used for unattended connections.
Tip: Use a password manager to generate a password that meets complexity requirements. - 4
Disable or configure the random session password
If you want a consistent credential, disable the option that automatically generates a random password on each session. Confirm that the fixed Personal password will be used for unattended access.
Tip: If you must keep some randomness for specific sessions, document when and why it occurs. - 5
Enable two-factor authentication
Ensure the TeamViewer account used to access the host device has 2FA enabled. This adds a second layer of defense beyond the password.
Tip: Prefer authenticator-based 2FA over SMS where possible for better security. - 6
Test unattended access
From a separate device, initiate a connection to the host using the new Personal password. Verify that you can connect without manual approval and that the connection is secure.
Tip: Document the test results and verify audit logs after the test.
Your Questions Answered
What is the difference between TeamViewer's Personal password and the random session password?
The Personal password is a fixed credential used for unattended access, while the random session password changes with each connection. For reliable remote support, prefer a strong Personal password and disable automatic random passwords when appropriate.
The Personal password is fixed for unattended access, while the random password changes every session. Use a strong Personal password for consistent access and consider disabling the random password if you need predictable connections.
Can I set the same default password on multiple devices?
Yes, you can apply the same Personal password to multiple host devices, but this increases risk if the credential is compromised. Use a password manager and rotate credentials periodically, especially after personnel changes.
You can use the same Personal password across devices, but it raises risk if compromised. Rotate regularly and monitor access.
Is TeamViewer secure with a fixed password?
Fixed passwords are convenient but require strong protection measures, including 2FA and up-to-date software. Regularly audit access and ensure the password is not shared insecurely.
Fixed passwords can be secure if they’re strong, rotated regularly, and protected with two-factor authentication.
How do I enable two-factor authentication for TeamViewer?
To enable 2FA, sign in to your TeamViewer account, go to Security or Account settings, and follow the prompts to enable two-factor authentication with an authenticator app or hardware key.
Enable two-factor authentication in your TeamViewer account settings for extra protection.
What should I do if I forget the Personal password?
If you forget the Personal password, use the TeamViewer account recovery options and update the credential after regaining access. Maintain a secure backup in your password manager.
If you forget it, recover via your TeamViewer account and set a new strong password afterward.
