What is Paste?
Paste is a web-based text and code paste service. You put text into a form, choose a syntax-highlighting language and an expiration setting, and get back a page you can share with a link. Its distinguishing feature is time-limited storage: a paste can be set to disappear after a chosen window rather than living forever.
What you can do with it
- Store plain text, source code, or notes you would rather not send as an email attachment.
- Pick a language for highlighting from a very long list — common ones like Python, JavaScript, SQL, PHP, C# and HTML, plus dozens of niche options such as VHDL, COBOL, Fortran, Prolog and several assembler dialects.
- Set an expiration: never, a short window (minutes or an hour), or longer periods.
- Mark a paste as "view once," so it is consumed on first reading.
- Keep pastes tied to an account, with guest posting and login/registration options available.
Who it suits
Developers and sysadmins sharing a stack trace, config snippet or log excerpt; students and teachers exchanging code; anyone who needs to hand a short block of text to someone else without setting up file sharing. The expiration and view-once controls make it a reasonable fit for short-lived credentials, tokens or drafts you want to circulate briefly.
Trade-offs to weigh
A paste service is not a secure secret manager. View-once and expiry reduce the exposure window, but they do not encrypt the content for you, and anyone with the link can read it while it is live. For passwords, API keys or personal data, prefer a tool built for secrets or share through an encrypted channel. Also consider whether you need the paste to persist: if a colleague will read it next week, an expiry of an hour is the wrong choice.
A practical next step
Before pasting, decide two things: how long the recipient needs access, and whether the content is sensitive. If it is sensitive and short-lived, set the shortest expiry that still works and use view-once; if it is code you want reviewed later, use a longer expiry or an account so you can find it again. For a general-purpose alternative with a similar model, see Pastebin.
How do I create a new paste on Paste?
Open Paste and use the New Paste area: enter or paste your text into the editor, choose a syntax highlighting mode if needed (there is an Autodetect option plus a long list of languages and formats), set an expiration such as Never, 10 Minutes, or 1 Hour, then select Paste. If you want the content to disappear after the first viewing, enable View Once before submitting.
Useful choices to make before pasting:
- Highlighting: Autodetect (experimental) is convenient for mixed or uncertain content; pick a specific language or format when you want predictable formatting.
- Expiration: Choose a short window for temporary sharing, or Never only when the paste should remain available.
- View once: Best for one-time handoffs such as a token or configuration snippet, because the recipient cannot reopen it later.
- Account: You can paste as a guest, or log in/register if you want your pastes associated with an account.
A practical example: for a one-hour code review link, paste the code, select the relevant language, set expiration to 1 Hour, and share the resulting link. If it contains a password or API key, use View Once and confirm the recipient is ready to open it immediately.
Can I set an expiration time for my pastes?
Yes. Paste lets you choose an expiration for each paste, and the options shown include Never, View Once, 10 Minutes, and 1 Hour, with 1 Day visible as the list continues. "View Once" is a different kind of limit: instead of expiring after a clock interval, the paste is meant to disappear after being viewed a single time.
Which expiration to pick
- Never — best for reference material you want to keep returning to, such as a config file or a snippet you link from documentation. The trade-off is that it stays available indefinitely, so don't use it for anything secret.
- 10 Minutes / 1 Hour — useful for handing text to someone in a live chat or a shared screen session, where the paste only needs to survive the conversation.
- 1 Day — a reasonable middle ground for sharing code with a teammate who may not look at it immediately.
- View Once — for one-time secrets, like a temporary password or a token. Use it when the recipient is ready to read it right away; if they close the tab or the read fails, the content may be gone.
Practical scenario
Suppose you're pairing with a colleague and need to pass a long SQL query that's awkward to paste into chat. Set 1 Hour, send the link, and let it lapse on its own rather than remembering to delete it later. If instead you're sending an API key, use View Once and tell the recipient to have the destination field ready before opening it.
Next step
Before you paste anything sensitive, decide two things: how long the recipient realistically needs access, and whether a single view is enough. If you're unsure, choose the shortest interval that still works — you can always create a fresh paste. For comparison with other paste tools that offer similar expiry controls, see Pastebin.
Is it possible to password-protect a paste?
Password protection is not offered as a paste-level option on Paste. The creation form lists Expiration and View Once as the controls you can set, and neither restricts access with a password. Account login exists on the site, but that protects your account, not an individual paste.
If you need to share something sensitive, the practical path is to treat the paste as public for its lifetime and limit exposure another way:
- Use "View Once" so the paste disappears after a single viewing, which reduces the window for anyone else to read it.
- Use the shortest workable expiration (10 minutes or 1 hour) instead of Never.
- Share the link only through a private channel, and avoid pasting credentials, keys or personal data you would not want indexed or copied.
- Encrypt before pasting if the content is genuinely confidential: put the ciphertext in the paste and send the passphrase separately. That gives you real access control even without a built-in password field.
For comparison, some paste services do offer client-side encryption or password locks — for example PrivateBin and Pastebin (the latter behind a paid tier). If password protection is a hard requirement, choose one of those rather than relying on expiry alone.
Next step: decide whether "View Once" plus a short expiry is enough for your content. If not, encrypt the text yourself or move to a service with an actual password or encryption feature.
What programming languages are supported for syntax highlighting?
The site uses a syntax-highlighting engine with a very wide language list, so you can paste almost any common language and get colored code. It also offers an "Autodetect (experimental)" option that tries to guess the language for you.
H3. What's supported The list is long and spans several families:
- Mainstream languages: C, C++, C#, Java, JavaScript, TypeScript (via related modes), Python, Ruby, PHP, Go, Rust (via related modes), Swift, Kotlin, Scala, Perl, Lua, R, MATLAB, SQL, and shell/Bash.
- Web and markup: HTML 4.01, HTML 5, CSS, XML, Markdown, YAML, JSON, INI, and configuration formats such as Nginx, Apache, and ProFTPd config.
- Databases and query languages: MySQL, PostgreSQL, Oracle SQL (8 and 11), PL/SQL, T-SQL, and SPARQL.
- Assemblers: ARM, Motorola 68000, Microchip, PIC16, Z80, 6502-style (via 64TASS/TASM), and others.
- Functional and academic: Haskell, OCaml, F#, Erlang, Clojure, Scheme, Lisp, Prolog, and Fortran.
- Scripting and automation: PowerShell, VBScript, AutoHotkey, AutoIt, and mIRC scripting.
- Legacy and niche: COBOL, Pascal, Delphi, Visual Basic, VB.NET, Ada, Fortran, and many more.
H3. Practical notes
- Autodetect is experimental, so it may mislabel unusual or mixed-language files. If colors look wrong, pick the language manually from the dropdown.
- The list is organized by category, which makes finding a language faster than scrolling alphabetically.
- Some entries are variants, such as "C++ (with QT extensions)" or "PHP (Brief)" — choose the closest match to your code.
- Plain Text is available when you don't want any highlighting.
For a quick test, paste a short snippet, leave the language on Autodetect, and compare the result with a manual selection. If the highlighting is off, switch to the specific language before sharing the paste.
For an alternative with a similarly broad language list, see Pastebin.
How does the 'View Once' option work?
The "View Once" option makes a paste available for a single viewing rather than for a fixed time window. You choose it from the same expiration menu where you would otherwise pick a duration such as 10 minutes or 1 hour; instead of the paste lasting until a clock runs out, it is meant to be consumed the first time someone opens it.
What that means in practice
- The paste is created normally and you get a link to share.
- The recipient opens the link once and reads the content.
- After that first view, the paste is no longer retrievable through the link.
Trade-offs to weigh
| Situation | View Once | Timed expiration |
|---|---|---|
| One recipient, one read | Good fit | Works, but the paste lingers until the timer ends |
| Several people need the same text | Poor fit — only the first reader gets it | Better |
| You want to re-read it yourself later | Poor fit | Better |
| You want the content gone quickly regardless of readers | Reasonable | Also reasonable |
The main risk is accidental consumption: if you open your own link to check it, or a chat app or security scanner previews the URL, the single view may be used up before your intended recipient sees it. Send the link only to the person who needs it, and avoid pasting it somewhere that auto-fetches links.
For anything you need to keep for reference, use a timed expiration instead, and treat both options as short-lived conveniences rather than secure storage — the site itself describes pastes as suitable for text, source code or sensitive data held for a set period, so for genuinely confidential material a dedicated encrypted channel is the safer route. If you want a second opinion on how a particular paste behaves, create a throwaway test paste with harmless content and open it once to confirm the link stops working.
