Forgejo's `basic` and `oauth2` authentication methods perform five distinct types of authentication:
- Username and password authentication
- Personal access tokens
- OAuth2 access tokens
- Forgejo Action's `${{ forgejo.token }}` -- task-based static tokens
- Forgejo Action's `${{ env.ACTIONS_RUNTIME_TOKEN }}` JWT, which is the authentication method used for `upload-artifact` (mirroring GitHub's implementation)
`basic` and `oauth2` both supported almost all of these methods, resulting in quite a bit of code duplication between them. This PR splits personal access tokens into `access_token.go`, Action's task-based tokens into `action_task_token.go`, and Action's JWT tokens into `action_runtime_token.go`.
**Note:** There is one peculiar side-effect that is worth discussing. Previously, `Authorization: Basic ...` was handled by one complex code path in basic.go, and `Authorization: Bearer ...` was handled by another in oauth2.go, and if authorization failed and a 401 was returned, a single error message would be returned to the user. Now, as multiple authorization methods may look at `Authorization: Basic ...` and provide their own reason why authorization didn't work, a 401 response has multiple reasons for a lack of authorization listed:
```
401 Unauthorized
...
failure to authenticate with oauth2 access token: not a JWT
Basic authorization is not allowed while having security keys enrolled
access token does not exist [sha: notpassword]
task with token "notpassword": resource does not exist
```
A couple tests have been adapted to check that the result contains their expected response, rather than is equal-to or prefixed-with their expected result. This is caused by the "auth group" joining together any "invalid credentials" errors, and, to a certain extent it is useful to understand why the authorization request failed. But it's a bit obscure as well.

resolves#8549
This PR add a config to enforce 2FA for the whole Forgejo instance. It can be configured to `none`, `admin` or `all`.
A user who is required to enable 2FA is like a disabled user. He can only see the `/user/settings/security`-Page to enable 2FA, this should be similar to a user which needs to change his password. Also api and git-commands are not allowed.

- Currently the TOTP secrets are stored using the `secrets` module with
as key the MD5 hash of the Secretkey, the `secrets` module uses general
bad practices. This patch migrates the secrets to use the `keying`
module (#5041) which is easier to use and use better practices to store
secrets in databases.
- Migration test added.
- Remove the Forgejo migration databases, and let the gitea migration
databases also run forgejo migration databases. This is required as the
Forgejo migration is now also touching tables that the forgejo migration
didn't create itself.
- This unifies the security behavior of enrolling security keys with
enrolling TOTP as a 2FA method. When TOTP is enrolled, you cannot use
basic authorization (user:password) to make API request on behalf of the
user, this is now also the case when you enroll security keys.
- The usage of access tokens are the only method to make API requests on
behalf of the user when a 2FA method is enrolled for the user.
- Integration test added.
Fixes#27819
We have support for two factor logins with the normal web login and with
basic auth. For basic auth the two factor check was implemented at three
different places and you need to know that this check is necessary. This
PR moves the check into the basic auth itself.
