Hvis jeg glemmer min kode, kan jeg ikke logge ind.

Hvis means if. It introduces a condition:

• Hvis jeg glemmer min kode = If I forget my password/code

It is used for real or possible conditions. In this sentence, the speaker is saying what happens under that condition.

A useful comparison:

• hvis = if
• når = when

So:

• Hvis jeg glemmer min kode... = if I forget it
• Når jeg glemmer min kode... = when I forget it, implying it does happen

Because jeg is the subject, and the verb must be in a finite form. Glemmer is the present tense of at glemme.

• at glemme = to forget
• jeg glemmer = I forget / I am forgetting

In Danish, after hvis, you still use a normal conjugated verb:

• Hvis jeg glemmer...
• not Hvis jeg glemme...

Also, Danish often uses the present tense where English might also use present tense in an if-clause:

• If I forget my password, ...
• Hvis jeg glemmer min kode, ...

Because in a subordinate clause introduced by hvis, Danish normally keeps the basic word order:

• subject + verb
• jeg glemmer

So:

• Hvis jeg glemmer min kode is correct.

The inverted order glemmer jeg is not used here.

A very important pattern:

• Main clause: often verb in second position
• Subordinate clause: more regular subject + verb order

Because kode is a common gender noun in Danish, and common gender nouns take min for my.

• en kode = a code/password
• therefore: min kode = my code/password

Compare:

• en bil → min bil
• et hus → mit hus

So the possessive must match the gender of the noun:

• en-word → min
• et-word → mit

In this context, kode usually means a password, PIN, or login code, depending on the situation.

Danish often uses kode in places where English might be more specific. So the exact translation depends on context:

• password
• PIN
• access code

If this is about logging in to an account, English would often naturally say password even though the Danish says kode.

Because Danish main clauses follow the verb-second rule. When the sentence begins with the if-clause:

• Hvis jeg glemmer min kode

that whole clause takes the first position. Then the finite verb of the main clause must come next:

• kan

So the main clause becomes:

• kan jeg ikke logge ind

This is a very common pattern in Danish:

• Hvis det regner, bliver jeg hjemme.
• Når han kommer, starter vi.

If the main clause stood alone, it would be:

• Jeg kan ikke logge ind.

But after a fronted clause, inversion happens:

• ..., kan jeg ikke logge ind.

In the main clause, ikke usually comes after the finite verb and the subject when inversion has happened.

Here the order is:

• kan = finite verb
• jeg = subject
• ikke = not
• logge ind = infinitive verb phrase

So:

• kan jeg ikke logge ind

This may feel different from English, but it is normal Danish word order.

Compare:

• Jeg kan ikke logge ind.
• Hvis jeg glemmer min kode, kan jeg ikke logge ind.

In both cases, ikke is placed before the infinitive phrase logge ind.

Logge ind is a verb expression meaning to log in or to sign in.

It is written as two words:

• at logge ind = to log in
• jeg logger ind = I log in
• jeg kan ikke logge ind = I cannot log in

This is similar to English, where log in is also often treated as a verb + particle combination.

You will often see forms like:

• logger ind
• loggede ind
• har logget ind

In normal modern Danish, logge ind is the natural and common expression.

You may sometimes encounter related forms such as indlogning for login/sign-in, but as a verb, learners should generally use:

• at logge ind

So this sentence is idiomatic as it stands:

• Hvis jeg glemmer min kode, kan jeg ikke logge ind.

Danish often uses the present tense to talk about future or general situations, especially after hvis.

So:

• Hvis jeg glemmer min kode, kan jeg ikke logge ind

can mean a general truth or a future possibility:

• If I forget my password, I can’t log in.

Danish does have ways to express the future, but they are often unnecessary when the context is clear.

Yes, in standard Danish writing, a comma is normally used between the if-clause and the main clause:

• Hvis jeg glemmer min kode, kan jeg ikke logge ind.

This helps show the boundary between:

• the condition: Hvis jeg glemmer min kode
• the result: kan jeg ikke logge ind

Comma rules in Danish can vary a little depending on comma style taught or used, but in a sentence like this, the comma is standard and expected.

Not always. Danish has different words depending on the meaning of if.

Use hvis for a condition:

• Hvis jeg glemmer min kode... = if I forget my password...

Use om for whether/if in indirect questions:

• Jeg ved ikke, om jeg kan logge ind.
• I don’t know whether/if I can log in.

So in this sentence, hvis is correct because it expresses a condition, not uncertainty between two possibilities.

The main clause alone would be:

• Jeg kan ikke logge ind.
• I can’t log in.

When the conditional clause is added at the front, Danish changes the word order in the main clause:

• Hvis jeg glemmer min kode, kan jeg ikke logge ind.

So this is a very useful contrast:

• Jeg kan ikke logge ind.
• Hvis jeg glemmer min kode, kan jeg ikke logge ind.

That shows the effect of the verb-second rule clearly.
