Say it like this
- Generate a token for the user session
- The token has expired, please log in again
- Validate the API token before processing the request
- Store tokens securely in the database
Use it at work
Auth
- The access token expires after an hour.
- Send the token in the header.
Security
- Don't commit tokens to the repo.
- Rotate the API token.
AI
- The prompt is 2,000 tokens.
- Costs are based on tokens.
Don't say this
Token is a noun in this context, not a verb. You do not token something; you generate, issue, or validate a token.

Real examples(3)
- in a standup
"We need to implement token refresh logic so users don't have to re-authenticate every hour."
- in a code review
"Make sure you're not hardcoding the API token in the source code; use environment variables instead."
- in a team meeting
"Our tokenization process breaks down user input into smaller units so the language model can understand it better."
More mistakes(2)
Handle with care. Token has multiple meanings depending on context (authentication, cryptocurrency, language processing). Be specific about which type you mean.
- ✕We use tokens for security because they are passwords.✓We use tokens for security because they're temporary credentials that provide better security than storing passwords.
Tokens are different from passwords; they are temporary, often single-use, and more secure than reusing the same password.
- ✕The API token is stored in the front-end code.✓The API token should be stored securely on the backend, never in front-end code.
Storing tokens in client-side code exposes them to security risks. This is a critical mistake in real development.
Other forms(3)
- token noun
"The authentication token grants access to the user dashboard."
- tokens noun
"We store multiple tokens in the cache for different API endpoints."
- token-based adjective
"Our system uses token-based authentication instead of session-based authentication."
Often used with(6)
- access token · A token that grants permission to access protected resources. Used frequently in OAuth and API contexts.
- refresh token · A token used to obtain a new access token without re-authenticating. Discussed in authentication system design.
- API token · A credential used to authenticate requests to an API. Common in backend and integration discussions.
- bearer token · A token passed in HTTP headers to authenticate API requests. Standard in REST API documentation.
- token expiration · The time limit after which a token becomes invalid. Important for security and session management.
- tokenize · To break text into tokens or to generate a token. Used in NLP and authentication contexts.
Similar words(3)
- credential · More general term. A token is a specific type of credential, usually temporary and unique.
- key · Sometimes used interchangeably in API contexts, but token is more specific for user authentication.
- certificate · Similar security purpose but typically used for server-to-server authentication, not user sessions.

Questions(5)
- What does token mean in software engineering?
- A token is a unique credential or data unit used for authentication, authorization, or text processing. In authentication, it is a string that proves a user is logged in without requiring constant password entry. In machine learning, it is the smallest unit of text processed by a model.
- How do you use token in a sentence at work?
- Common workplace usage: Please send your API token in the request header. The access token has expired, so you need to log in again. The tokenization process splits the input into words for processing.
- Is token formal or informal?
- Token is neutral in formality. It is used equally in formal documentation, code comments, meetings, and casual conversation among tech professionals.
- What is the difference between a token and a password?
- A password is something you create and remember. A token is generated by the system, is temporary, and often expires. Tokens are more secure for API requests because they limit exposure if compromised.
- Why do developers use tokens instead of passwords?
- Tokens offer better security because they can expire, be revoked, and have limited scope. They also reduce password reuse across systems and allow fine-grained permission control.
