# Authentication

## Phrase Platform API tokens

<Note>Preferred method – use this for a single, consistent way to access all Phrase Platform APIs.</Note>

Generate a Phrase Platform JWT token as described [here](/en/api/platform/authentication), then pass it in the `Authorization` HTTP header in every subsequent API call (`Bearer`).

## ApiToken

Get a token from `auth/login` [endpoint](/en/api/tms/latest/authentication/login) and then pass it in the `Authorization` HTTP header in every subsequent API call.
