+This post goes over how to generate a random token with bash:
+
+- [Node.js](#nodejs)
+- [Python](#python)
+- [SHA](#sha)
+- [openssl](#openssl)
+- [uuidgen](#uuidgen)
+
+## Node.js
+
+Generate UUID:
+
+```sh
+node -p 'require("crypto").randomUUID()'
+```
+
+Output:
+
+```
+9396db12-8449-41d6-871d-3237f9635fe3
+```
+
+## Python
+
+Generate URL-safe Base64 (no `+` and `/`):
+
+```sh
+python3 -c "import secrets; print(secrets.token_urlsafe(32))"
+```
+
+Output:
+
+```
+7qwVk5Khe484EboUj_qI8pGcD-M-63Er1jK3qZS0R68
+```
+
+## SHA
+
+Generate hash::
+
+```sh
+date | md5
+```
+
+Output:
+
+```
+332690933cc2bebed106ca4e1c13e278
+```
+
+For a longer hash, replace `md5` with an algorithm below:
+
+- `sha1`
+- `sha224`
+- `sha256`
+- `sha384`
+- `sha512`
+
+## openssl
+
+Generate 64 hex characters:
+
+```sh
+openssl rand -hex 32
+```
+
+Output:
+
+```
+f48c74486edad3a4c1d1018dcd2f60443e38d43348e14a5be60e46f16cee0fc4
+```
+
+Generate Base64:
+
+```sh
+openssl rand -base64 32
+```
+
+Output:
+
+```
+RzFILO5Z8S8VMJDoP7RniyjD8WR6N9ES+y665N8/nC8=
+```
+
+## uuidgen
+
+Generate a random-based UUID (UUIDv4):
+
+```sh
+uuidgen
+```
+
+Output:
+
+```
+A004F406-00AF-4C39-9830-32668C49744B
