אל תשתפי קוד חד-פעמי.

אל is the usual word for a negative command in Hebrew: don’t ...

So:

• אל תשתפי = don’t share
• לא תשתפי would usually sound like you will not share or a statement/prediction, not a direct command.

So in warnings and instructions, אל + future form is the normal pattern.

In Hebrew, negative commands are normally made with:

אל + future tense form

So even though the meaning is imperative in English, the Hebrew structure uses the future form:

• שתפי! = Share! (positive command, feminine singular)
• אל תשתפי! = Don’t share! (negative command, feminine singular)

That is completely normal Hebrew grammar.

תשתפי is addressed to one female.

So this sentence is speaking directly to a woman or girl.

Other versions would be:

• אל תשתף קוד חד-פעמי. = to one male
• אל תשתפו קוד חד-פעמי. = to more than one person / a general plural address

So the -י ending here is a clue that the speaker is talking to feminine singular.

The dictionary form is לשתף = to share.

The root is ש-ת-ף.

In this sentence:

• לשתף = to share
• תשתפי = you (feminine singular) will share / in this context, with אל, don’t share

So if you look the verb up, you would search for לשתף.

קוד means code.

It is a modern borrowed word, basically the same idea as English code, but pronounced in Hebrew style.

In this sentence it refers to something like a verification code, login code, or one-time passcode.

Literally, חד-פעמי means something like one-time or single-use.

It is made from:

• חד = one / single
• פעמי = related to time/occurrence

So קוד חד-פעמי means:

• a one-time code
• a single-use code
• often in practice: a one-time passcode

Because קוד is a masculine singular noun, and the adjective has to agree with it.

So:

• קוד חד-פעמי = masculine singular
• if the noun were feminine, the adjective would change:
  • סיסמה חד-פעמית = a one-time password

This is normal Hebrew adjective agreement: the adjective matches the noun in gender and number.

The hyphen links the two parts of a compound adjective.

So חד-פעמי is treated as one expression meaning one-time / single-use.

In everyday typing, you may also see חד פעמי without the hyphen, but חד-פעמי is a very standard written form.

To one man, you would say:

אל תשתף קוד חד-פעמי.

So the only change is the verb form:

• תשתפי = to one woman
• תשתף = to one man

The rest of the sentence stays the same.

The common plural version is:

אל תשתפו קוד חד-פעמי.

This is the form you would often see in public instructions, app messages, or security warnings when speaking to users in general.

Because קוד here is indefinite: a one-time code, not the one-time code.

Hebrew uses את before a definite direct object.

So compare:

• אל תשתפי קוד חד-פעמי. = Don’t share a one-time code.
• אל תשתפי את הקוד החד-פעמי. = Don’t share the one-time code.

When the object is indefinite, there is no את.

A simple pronunciation guide is:

al teshatfi kod chad-pa'ami

A few notes:

• אל = al
• תשתפי = teshatfi
• קוד = kod
• חד-פעמי = chad-pa'ami or khad-pa'ami, depending on how you represent ח

The ח sound is the throaty Hebrew sound that English does not really have.

Yes, very natural.

It sounds like a direct instruction such as a warning from a bank, website, or app.

Depending on style, Hebrew security messages might also use more formal wording like:

• אין לשתף קוד חד-פעמי. = One must not share a one-time code.
• לעולם אל תשתפי קוד חד-פעמי. = Never share a one-time code.

But the original sentence is perfectly normal and clear.
