What Gmail app passwords are and why they matter
Gmail app passwords are 16-digit codes generated for apps and devices that do not support modern sign-in methods like two-step verification prompts.
If you are trying to learn how to check Gmail app passwords, the first thing to know is that Google does not display a saved list the way a password manager might; instead, you review them from your Google Account and manage them there.
This matters because app passwords are often used by older email clients, scanners, printers, desktop mail apps, or third-party tools that connect to Gmail through IMAP or SMTP.
Once you understand where they live and how Google controls them, the process becomes straightforward.
Can you view an existing Gmail app password?
In most cases, you cannot reveal an app password after it has been generated.
Google typically shows the code only once at creation time for security reasons.
After that, you can check whether app passwords exist, see which app or device they were created for, and remove or replace them if needed.
So when people search for how to check Gmail app passwords, they usually mean one of three things: confirm that app passwords are enabled, see which ones are active, or generate a new one for a specific device.
How to check Gmail app passwords in your Google Account
Follow these steps from a desktop browser or mobile browser while signed in to the correct Google Account.
- Go to your Google Account page.
- Select Security.
- Under How you sign in to Google, look for 2-Step Verification.
- If 2-Step Verification is not turned on, app passwords will not be available.
- After confirming 2-Step Verification, look for App passwords.
- Open App passwords to view the apps and devices that have been assigned a password.
Google may ask you to sign in again for verification.
If the App passwords option is missing, your account may not qualify, or an organization admin may have disabled it.
Where to find the App passwords option in Gmail
The App passwords setting is not inside the Gmail inbox itself.
It lives in the Google Account security settings, which is easy to miss if you only search through Gmail menus.
For personal Google Accounts, the path is generally:
- Google Account
- Security
- 2-Step Verification
- App passwords
For Google Workspace accounts, availability depends on the administrator’s security policy.
Some organizations disable app passwords entirely because they are less secure than modern authentication methods such as OAuth 2.0.
How to know whether an app password is active
Inside the App passwords page, Google may show labels for the app and device you selected when you created the password, such as Mail on iPhone, Windows Computer, or Other.
This confirms that app passwords exist, even though the code itself is hidden after creation.
If you want to verify a specific app password, use the following checks:
- Confirm the intended app or device is listed.
- Check that the password was entered correctly in the mail client or device settings.
- Test sign-in or mail sync to confirm the app password works.
- Remove and recreate the password if the app stops connecting.
If the app can no longer connect, the issue may not be the app password itself.
Network restrictions, outdated IMAP settings, disabled access for less secure apps, or expired device tokens can also be involved.
How to generate a new Gmail app password
If you cannot retrieve the old password, create a new one and replace the stored password in the app or device.
- Open your Google Account.
- Go to Security.
- Turn on 2-Step Verification if it is not already enabled.
- Select App passwords.
- Choose the app and device from the dropdown menus, or select Other and enter a label.
- Select Generate.
- Copy the 16-digit password and paste it into the app’s password field.
Google may require you to create a separate password for each app or device combination.
This makes it easier to revoke access later without affecting everything else.
How to remove or replace Gmail app passwords
Removing old app passwords is one of the best ways to reduce account risk.
If you no longer use a device or app, delete its app password from your Google Account.
To remove one, return to App passwords, find the entry, and choose Remove.
If you suspect unauthorized access, remove all app passwords and then generate new ones only for trusted devices.
Useful times to replace an app password include:
- After changing your Google Account security settings
- When an email client repeatedly asks for credentials
- After switching phones, computers, or printers
- When a shared or old device should no longer connect
Common problems when checking Gmail app passwords
The App passwords option is missing?
If you do not see App passwords, the most common reasons are that 2-Step Verification is off, your account is managed by an organization, or your account uses a security method that does not support app passwords.
Some newer protection setups rely on passkeys, security keys, or OAuth-based app access instead.
The app password works on one device but not another?
Each app password is meant for a specific connection.
Reusing one code across multiple apps can cause confusion, especially if an app stores the wrong account profile or sync method.
Create separate passwords and label them clearly.
The app asks for the password again?
That can happen if the app stores credentials incorrectly, if the mail provider settings are outdated, or if the app password was revoked.
Verify IMAP or SMTP settings, then sign in again with the current app password.
Security best practices for Gmail app passwords
App passwords are convenient, but they should be used carefully because they bypass the normal second-factor prompt after creation.
Follow these practices to limit exposure:
- Use app passwords only when an app does not support modern sign-in.
- Create one password per app or device.
- Label passwords clearly so you know what to revoke later.
- Delete passwords for devices you no longer use.
- Prefer modern authentication methods such as OAuth 2.0 when available.
- Keep 2-Step Verification enabled on the account.
If you use Google Workspace, coordinate with your administrator before changing authentication settings.
Some organizations require security keys, passkeys, or approved third-party apps instead of app passwords.
When to use an app password instead of your regular Gmail password
Use an app password when an older app or device cannot complete Google’s normal sign-in flow.
Common examples include desktop email clients, legacy mail apps, scanners, and some smart home or office devices that only accept a basic password field.
Do not use your main Google Account password in those apps if app passwords are supported.
A separate app password limits the impact if that device is compromised and makes account management much easier.
Quick checklist for checking Gmail app passwords
- Sign in to the correct Google Account.
- Open Security in account settings.
- Confirm 2-Step Verification is enabled.
- Open App passwords to review active entries.
- Use the listed labels to identify each app or device.
- Remove unused passwords and generate new ones when needed.
If you are troubleshooting an older email setup, printer, or third-party app, checking Gmail app passwords is often the fastest way to rule out authentication problems without changing your main account password.
