Ich habe meine Geheimzahl vergessen. or Ich vergesse meine Geheimzahl.

[Rams.1]

Ich habe meine Geheimzahl vergessen. or
Ich vergesse meine Geheimzahl.

Which is correct sentence in above and what is the different. What is the meaning change if we use habe in first sentence? Please help me to understand.

[Fabfifties]

1st sentence : I have forgotten my PIN.

2nd sentence : I forget my PIN / I'm forgetting my PIN

[MykeDeWolf]

The first one is past tense, the second one is present, I think.

[Max.Em]

past = Perfekt here.

[gmbka]

Vergessen in the present tense always is modified. Ich vergesse haeufig, immer, oft, nie.
